How to Fix: Rust Bubble Under Paint from a Rock Chip Around WIndshield

  • 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.

    Here's a list of products that I used:
    • Wax & Grease Remover
    • Blue shop towels
    • Q-tips
    • Wire wheel brush
    • Automotive masking tape
    • Cargroom Cream body filler, hardener
    • Mixing board & Spreader
    • Dura-Block sanding block
    • Sand paper: 80, 180, 320, 400, 600 Grit
    • Cargroom spot putty
    • Duplicolor self etching primer
    • Duplicolor filler primer
    • Duplicolor Perfect Match paint
    • Duplicolor Lacquer Clear Coat
    • Tack Cloth
    • Orbital buffer & terry cloth pad
    • Meguiars light cutting compound/polish
