Scale rust occurs when you leave surface rust to continue the corrosion process until it pits the metal. Chemical reactions cause rust that begins to damage the metal of the body panel itself.

Eventually, scale rust will work its way through the surface of a body panel and affect the integrity of the metal itself.

Step 3: Wipe away dust

Wipe away any remaining dust or lint with a lint-free cloth before applying the paint manufacturer’s prep solvent.

Step 4: Apply epoxy primer

Apply epoxy primer first, followed by filler primer. Filler primer should be sprayed in thicker applications to cover the entire restoration area. Blend the can into the surrounding painted area by moving it slightly away from the surface. Use a self-etching epoxy primer as your initial layer to ensure a solid connection to bare metal.

Step 5: Apply lacquer filler

Wet 1,000-grit sandpaper is used to grind the epoxy primer. Allow drying after washing with clean water. Wipe the cured epoxy primer clean with a lint-free cloth before applying two to three coats of lacquer filler primer, leaving time for each application to dry. Allow at least one hour for the lacquer primer to dry to the touch before sanding.

Step 6: Sand the whole repair

Use 320-grit sandpaper, sand drips, and sags, then sand the entire repair area to a smooth finish. Smooth the primer and feather the edges with wet 600-grit sandpaper. In the end, sand the whole repair, including the blended areas, with wet 1,000-grit sandpaper.

Step 7: Spray the repaired area

Begin at the bottom of the repair and apply the color coat in left-to-right rows, roughly one-third overlapping each pass. In two to three coats, gradually work the color into the repair and surrounding areas.
