2. Work only at temperatures above 12 degrees, but not in the open sun and not in strong winds.
Rust removal
1. Tape the contour of the repair site with protective tape (tezakrepp), so as not to inadvertently damage the surrounding paintwork.
2. Remove all visible rust, as well as rust hidden under the bubbles, with a triangular file or screwdriver, and coarse 120 grit sandpaper.
3. Sand the edges around the damaged area with a 1-2 cm overhang on the undamaged surface with 320 grit sanding paper.
4. Galvanized body parts should, if possible, be cleaned only to the ground, and not to the zinc coating.
Applying an anti-corrosion primer ("Primer")
1. Clean the place of repair from dust and grease with a nitro thinner and a clean cloth and allow to dry.
2. To avoid incompatibility issues, "Primer" must be from the same manufacturer as the paint being applied. Otherwise, the paint will bubble and wrinkle.
3. Spray "Primer"ohm from a distance of about 25 cm in a very narrow, but covering the surface, jet. Cover the surrounding surfaces with masking tape and newsprint to avoid aerosol mist.
4. After 10-15 minutes of airing, spraying can be repeated. If putty is to be applied at the repair site, before "Primer" should dry well.
Puttying
There are 2 types of putties: two-component putty and thin putty. Two-component putty is mixed before processing and hardener. It hardens quickly and needs to be applied quickly. It is used to level large irregularities in the metal. Thin putty is viscous, which leveled small surfaces. It can be applied in several layers. Both types of putty are available in tubes and jars, thin putty is also available in aerosol packaging.
Attention! Although cans of putty are often written recommending direct application of the putty to the metal, in any case, it is advisable to prepare it with an anti-corrosion "Primer"ohm.
1. Apply a two-component putty to the straightened or glued with fiberglass place and allow to harden. Follow the manufacturer's recommendations.
2. After hardening, smooth out the unevenness manually or with a vibration grinder. When doing this, use sanding paper with grain "180". Now you can already apply waterproof sanding paper. In this case, moisten the repair site with plenty of water from time to time (sponge).
3. In conclusion, thoroughly wipe the repair site and allow to dry.
4. Using a wide elastic plastic spatula, apply a thin layer of putty to the repair site and allow it to harden for at least 2 hours. On large curves and contours, it is recommended to apply putty from an aerosol can.
5. Depending on the thickness of the applied layer, the thin putty should dry out from 2 to 3 hours.
Sanding
1. Sanding paper comes in a variety of grit sizes. The lower the number, the rougher the paper. For sanding a two-component putty, a grit of 180 to 240 is recommended; filler putty and old paint are sanded with 360 grit water. For the final sanding step with water, 600 grit sanding paper is recommended.
2. Sand the puttied places with 360 grit paper, keeping a sponge constantly over the repair area. From time to time, immerse the sponge in clean water.
3. For subsequent wet fine sanding, a special waterproof finishing paper with a grit of 600 is best suited, while the surrounding surface is also sanded. At the same time, grind only in the direction of the longitudinal dimension of the vehicle; however, residual small sanding scratches in the top coat are less noticeable.
Cleaning
1. Before coating with paint, the sanded surface, as well as the surface around it two palms wide, must be freed from traces of grease and silicone. Silicone remover works best for this.
2. After sanding, carefully clean the repair area and carefully cover all surrounding parts of the car with newsprint and pecking tape. When painting the fenders, also protect the wheels and shock absorbers.
3. Try to glue the place of repair so that the painted surface would always be limited to the nearest molding or edge of the body, since a bump of paint appears along the edge of the pasting, if the gradual transition of the color to the original color is imperceptible, glue it at a distance from the place of repair in width two palms.
4. Moisten the floor to collect dust.
