How to Fix Rusted Body Panels on a 1981 Chevy Blazer
- 1). Scrape off the surface rust with a wire brush.
- 2). Create a paste using a mixture of one part lemon juice and two parts borax. Use a paper towel to apply the paste to the rust on the truck. Wait 30 minutes and scrub off the rust with a scrubbing pad. Clean the door panels with dampened paper towels.
- 3). Put on work gloves. Apply naval jelly using a paper towel. Let the naval jelly sit on the rust for 10 minutes. Wipe away the rust on the panel with a damp paper towel. Naval jelly is very effective in removing rust because it contains phosphoric acid. It can be purchased from a hardware store.
