How to put the car body on your own

Assuming the responsibility of assembling the car body yourself can be gratifying as well as difficult. Knowing the procedures is essential whether you’re working on a project car or restoring a vintage car. If you have the correct equipment, supplies, and patience, you can accomplish professional-quality results at home.

It’s critical to have a well-defined plan and workspace before you start. This entails assembling all required equipment and supplies, including paint, screwdrivers, wrenches, and safety gear. Ensure that your workspace is airy, light, and clean. A clean, organized workspace will facilitate and secure the process.

Examine the state of your car’s body first. Keep an eye out for any damage that needs to be fixed, such as dents or rust. Prior to continuing, these problems must be fixed. An empty canvas for your new paint job will result from sanding down the surface to get rid of rust and old paint. Don’t rush this step because a strong finish depends on careful planning.

After the body is prepared, you can start assembling it. This entails lining up doors, panels, and other parts precisely. You’ll avoid headaches later on if you take your time and make sure everything fits properly. For part installation, use premium adhesives and fasteners. Recall that accuracy and focus on details are essential.

The final step that turns all of your hard work into a finished product is painting the body of your car. Select a premium paint and apply it according to the manufacturer’s instructions. One thick coat will not work as well as several thin coats. During this stage, patience will pay off with a polished, seamless finish.

Tools and materials for putty

In order to assemble the car by hand, you must first gather all required supplies, equipment, and consumables. The following is a rough list of accessories for auto repair:

  • sandpaper with varying degrees of grain;
  • bar for fastening sandpaper;
  • degreasing with the possibility of removal of silicone or solvent;
  • anticorus;
  • comfortable spatulas of different sizes;
  • capacity for kneading putty;
  • suitable putty or several types of putty;
  • manifold coating;
  • protective gloves;
  • respirator;
  • rags and napkins.

A reverse hammer, spotter, or kiyanka may be needed in cases of severe bodily injuries. It will enable the dent to be straightened as much as possible, returning the body to its original shape. Regarding sandpaper, the granularity of the material is typically prepared between 40 and 360, depending on the necessary base processing quality.

Preparation of the machine for putty

Preparing the surface for putty application is the most crucial step in sealing body defects for painting. First, measure the extent and depth of the defect by closely examining the damaged area. Let the water from the pre-washed car dry. Then, using P150 sandpaper that is fixed on the bar, they begin knocking gloss off.

They give the plot a thorough polish, remove any corrosion, exfoliate the paint, and shake the ends of the soil. This will lower the risk because the bar is kept right next to the surface. Excessive effort is ineffective. Soil is ground from the edges with a margin, making putty application easier. If there are any moldings or other components close by, they are paper taped in place beforehand to prevent damage.

It’s crucial to avoid overdoing primary grinding and getting down to the bare metal. It needs to stay covered in soil. By the time this phase is over, a shiny, rough surface ought to form. You can take the skin off the bar and hold it in your hand directly if that makes it more convenient. It is preferable to use Scotch-brown or P220 sandpaper in the most remote locations.

Proceed in this manner:

  • the surface is blown by air (if there is a compressor in stock) or eliminate dust particles with thoroughly smarting;
  • degrease the base with an antilicol or other type of degreaser in order to completely get rid of fats, dirt, spots;
  • if necessary, apply a special anti -corrosion agent on the base.

Since the putty process’s efficacy is largely dependent on the preparation phase, which accounts for nearly 50% of the process, it must be handled carefully.

The choice of putty

There are various putty options available on the market that are appropriate for fixing the body of an automobile. Their composition and purpose vary, and they are one- and two-component systems. If the material is not chosen with the repair’s goals and objectives in mind, a high-quality outcome will not be obtained. If the machine putty is available for purchase as pasta, it is already prepared for usage. As stated in the instructions, other mixtures must be diluted prior to application.

Rough putty

This substance is only applied in cases of severe physical harm. It can be used to seal dents, holes, and other kinds of deformations because a significant portion of it is made of fillers. Typically, metal shavings serve as a filler, enabling putty to firmly grasp the base and produce a very strong "patch."

Aluminum fillers are present in the priciest putty that is also the highest quality. These combinations are plastic, elastic, heat-resistant, flawlessly polished, and they can even seal the most severe, gruesome "injuries" on the body. You should not breed large portions of good puttys because they freeze in a matter of minutes. Mixtures that are gross can be topped with any other autoshpakles.

Fiberglass mixture

The most common use for this group’s putty funds is auto repairs. Due to the fact that they contain fiberglass, they are incredibly durable. The putty layer turns into fiberglass after it dries, making it ideal for grinding and other processing. He can effortlessly give him the ideal smoothness and shape. Fiberglass mixtures are particularly frequently used to seal corrosion damage and holes.

One drawback of fiberglass-based compositions is that they take longer to dry, but the end product is always worthwhile. They can be applied to both clean metal and old paintwork. The base only needs to be prepped in advance for the material to adhere to the substrate smoothly and firmly.

The finish putty

The final product is used to perfect evenness or remove minor flaws from the "patch." It can be used following a rough mixture and black repair work. Fillers make up a tiny portion of all finish putty. They are categorized as Fine or Nitro depending on the additives in the compositions; however, they essentially are identical in terms of processing efficiency and lightness.

The base is flawlessly prepared for painting with finish putty. They are elastic, have a good filling capacity, apply easily, and are not affected by temperature changes. Typically, they are applied to a pre-prepared base in a layer no thicker than 3 mm. The majority of materials have two components, which need to be diluted with a hardener before being used directly. Usually, the drying process takes no longer than thirty minutes.

Liquid putty

These days, materials with a liquid texture have the fastest processing rates. They affect a sizable portion of the body, are relatively light in structure, and close up even minor injuries. The surface takes around two hours to dry. To put it another way, these compositions are sprayed rather than coated, so you will need to buy a specialized handgun for work.

Universal putty

Similar putties are used for last-minute body repairs where lengthy processing and grinding are not possible. They blend the characteristics of coarse means and fine-grained (finish). Universal putty has a fairly high strength and elasticity, which helps to even out the surface and blend in nicely with paint and other compositions.

Putty work

The hardest thing to do is raise the car’s roof. The truth is that even the simplest mixture has mass and will push the component due to gravity. As a result, a tiny fossa is retained even after the work. Apply the material in strictly thin layers and allow them to dry in between. Various sizes are used for work. Typically, they start with a small tool and then use a wider spatula to overlap the strokes of the tool.

First, the material’s preparation. They familiarize themselves with the manufacturer’s instructions and elucidate the ratios required to mix putty. Components are typically assembled in metal or plastic containers. Blend the hardener and base together until the mixture is uniformly smooth and perfectly blended. For one layer, a small amount of putty is ready.

To align horizontal planes (hood and roof) try to take putty with aluminum powder, which are not afraid of constant heating in the sun and do not give shrinkage from expansion and compression. With the help of a spatula, apply the product to the surface, evenly distributing and leveling the layer. Movements should be smooth, directed from the bottom up. After stretching the first layer, take a break for at least 15 minutes and, if necessary, repeat the work. Wait for the material to dry completely, after applying a special developing coating and begin to grind. It is better for this purpose to use a grinding machine, but in its absence you can take the usual sandpaper with bar. Painting is carried out only after the area reaches ideal smoothness and evenness.

Putty of plastic elements

It’s crucial to carefully remove the gloss before putting putty on the bumper or other plastic parts. If you work on putty on metal, you should process it four times better to prevent putty from peeling off the surface. The base is cleaned with a degreaser once the grinding is finished, and only then is putty work begun.

Disposing the body of the machine

Make sure the "patch" is prepared for processing after it has dried completely. This is done using a fingernail, and the material is deemed dried up immediately if a white trace is still visible on the coating. In this instance, a large block works better for grinding because it can be rubbed unevenly with a smaller one. The only exception are places that are inaccessible and limited to using a small bar for operation. Soft bars are used when grinding the body’s bends, and they work best when used repeatedly.

Typically, the wizards use the P80 or P120 sandpaper for primary processing. Too much putty can be removed with rough paper. To avoid posing a risk to nearby surfaces, attempt to stay inside the site’s boundaries. In order to conceal even the smallest bumps, the putty process is repeated if the plane’s hole is now visible.

Following the initial grinding, they use air to blow the surface clean and proceed with P150 or even smaller sandpaper. Sandpaper P220 is used to treat the base prior to direct priming and staining.

Important nuances of the process

Skilled artisans are aware of several nuances that, when working with putty, enable you to achieve the ideal outcome:

  • The spatula is kept at an angle of 30-40 degrees to the plane;
  • make the coating as multi -layer as possible – this will reduce the risk of bloating, abruptions, failures;
  • When grinding, they always smoothly move from coarse -grained skins to fine -grained;
  • For grinding large zones, sandpaper is attached to the rubble in order to accelerate the process;
  • Check the base for smoothness only with the hand, and not visually;
  • If the putty is too thick, but there is no hardener, a little polymer is introduced into it from a repair kit with fiberglass;
  • On elements of the body subject to strong vibration, use the most elastic putty.

Drying of auto -patch

It is important to keep the workshop temperature between +10 and +20 degrees because below that it will be challenging to achieve the material’s outline. You can use infrared drying if needed. This improves the mixture’s drying speed and lowers the possibility of drawing a "patch" later on.

Is it possible to put a putty to paint

Material should not be applied to polished LKP. Factory paint is an exception, though it’s best to remove it completely (if at all feasible). The result of applying putty on an independent coating could be the composition swelling along with it. However, processing a paintwork directly from the factory will speed up the process overall and add more anti-corrosion protection.

Application of car putty on the ground

Apply the mixture only to epoxy-treated soil. If the part was cleaned to bare metal for an extended period of time—which typically occurs with extensive restoration work—it is preferable to do this. The metal becomes oxidized as a result, and epoxy soil gives it dependable defense against rust. You don’t need to apply the soil if the repair is done right away after washing the paint.

Finish layer of car putty

The entire renovated area is covered in this layer. It’s a thin, flawlessly leveled layer of putty. In the event that the upper portion of the layer proved to be sticky, a solvent treatment is applied before grinding.

Putty defects

Spots do occasionally develop on the coating. This is most likely the result of either adding too much of the last volume or poorly combining the base and hardener. You will need to apply another putty layer if a pore becomes visible because the composition was applied in a thick layer or imposed on a wet surface.
