Prepare the surface

First carefully washed the surface of the body. Wipe it dry and degrease with a solvent.Further, treated area should be sanded. For sanding large areas of the body it is better to use a sanding machine, and if the ground area is small, so the workload is quite able to make hand grinding the tool – bar or by a special plane. To prepare the metal to the drawing shpatlevochnoj weights typically use 80 grit abrasive paper. If the damage is small, the center of the dent to be processed by the already cited paper 80, and the outer region 120 grit paper with a fine grain of abrasive. Upon completion of the polishing of cleaned treated area of the body from dust, degrease it and apply a layer of anticorrosive primer.

Choose a product

To fill deep dents on the body, door or the bumper, it makes sense to opt for a rough two-component putty with aluminum dust or fiberglass. Align shallow dents easier two-component universal filler. Universal putty is used as the middle layer after layer of putty with fiberglass or aluminum dust. If you want to hide small cracks and chips, quite a final two-component putty, which is used as the last layer on top of universal. Final coat — the softest and most easily worked.

Preparing compound

"Easel" (a small sheet of tin) put a portion of putty, add the hardener and mix thoroughly pressing movements of the spatula to avoid air bubbles in the mixture. It is very important to mix the filler and hardener in the exact proportions indicated on the packaging filler. Ready for overlaying is plaster mixed until uniform and the disappearance of the pink streaks of hardener.

What kind of spatula is better

Difficult one to answer. The fact that metal spatula allows you to more accurately and evenly apply a layer of putty. But suitable only for flat surfaces. While rubber or silicon is indispensable for processing convex or concave surfaces and body parts. The use of metal spatulas are no special secrets, no, but for rubber and silicone it is a bit complicated. Do not buy too hard silicone spatula, do not forget that as soon as a little cold, reducing the temperature of the air it will become hard, almost like metal. Buying a rubber spatula it is important to select a tool of quality rubber, otherwise the rubber workspace very quickly start to unravel, until the appearance of gouges and pits.

Shpaklyuem body

Recruited spatula putty and pressing movements apply putty on the area being treated. Filling material on the surface of the body distributed confident and precise movements from top to bottom and from the center out. It is not recommended to apply a coat of sealer with a thickness more than 2 mm. If you need to close the dent to go deeper, instead of one thick layer shpaklevki it is better to apply several thin, causing them one after the other as the drying of the previous layer. The step of applying the putty is performed without undue haste, but without making smoke breaks, since the plaster "sets" of about 15-20 minutes.

the Grind

After drying of the putty is applied on the treated area slight contrasting colored coating. We use a dry color proofing coating, representing a fine-grained black powder. Grind the puttied area with abrasive paper P80. Which tool to use: manual or automatic, we have said above, at the beginning of the article. In the process of grinding control black coating will disappear. At the end of grinding before your eyes will appear the following picture – a bright spot putty sanded with small patches of flat paint on the bottom of small pits and cavities, which are not sick of sanding paper. If that's the way it looks, and it happens quite often, again knead the putty, apply it on the body, dry them, progressivem developing coating and sanding again. If upon completion of the sanding paper 80 grit, the entire surface of the filled area homogeneous light color without the black "control" points – congratulations, you did everything correctly and efficiently.

Remove dust and sanding again

Removed from the treated area all the dust. No matter what: air blow gun, vacuum cleaner, sticky wipe or brush, it is important that the working surface does not remain microscopic particles of the putty dust, deteriorating the adhesion of repair materials. Go to the grinding surface of the grinding paper 120 grit with finer abrasive grain, do not forget to periodically remove from the workspace dust.

For the final part – the final putty

Final knead the putty and apply a thin layer at the repaired site. After drying, the sanding surface of the sanding paper P180 brand first, and then Р240. To obtain a perfect surface I advise you to modify the repaired site and paper Р320. Sanding not only workspace, but also the adjacent areas with a paint coating. Very harmful is the Board to wet the work surface when grinding. Explain why. The water will penetrate the porous surface of the putty and go inland and back to the surface will only be back in a few weeks. This will lead to corrosion of the body, peeling of the putty and the formation of point in the paint bubbles. Upon completion of all putty-work and sanding before leaving the garage the repaired surface must be covered with a layer of primer. Now the vehicle's left to paint. When working always wear protective goggles, disposable gloves and protective mask! Remember – the dust trapped in your lungs, remain in them forever!
