In brief

Fix a rust bubble under paint caused by an old rock chip on your car’s windshield area by stripping the damaged section, filling pits with body filler, and blending the repair with the original paint. This method works for metal panels needing a seamless finish.

Key steps

  1. Clean the damaged area with wax & grease remover and Q-tips.
  2. Sand down rusted and bubbled paint using a wire wheel brush.
  3. Apply automotive masking tape to protect surrounding undamaged paint.
  4. Fill pitted areas with body filler mixed with hardener.
  5. Sand the filled area smooth with a sanding block and sandpaper.
  6. Prime the repair with self-etching and filler primer.
  7. Paint the area with Perfect Match paint and apply clear coat.
  8. Buff the dried repair with a light cutting compound for a seamless finish.

Questions & answers

What tools are needed for sanding and smoothing the repair?

A Dura-Block sanding block, variety pack of sandpaper, and an orbital buffer with Terry cloth pads.

Can this method be used on other metal car panels?

Yes, the process is suitable for repairing metal body panels with rust or paint damage.

Description from the creator

This all started with a stone chip in the paint and overtime, the exposed metal rusted and has bubbled beneath the surrounding paint. This is what happens if rock chips are left alone, so cover up chips with touch up paint as soon as you see them.
This chip got really bad and the rust has spread, causing the surrounding paint to bubble. Today I'll strip it down, fill the pitted areas with body filler and prime & paint the repair area to blend in with the original OEM paint on the rest of the roof.
