Paint stripper can be used on fiberglass, but it can't be allowed to sit too long or will start to eat through the fiberglass. It is best to look for a mild paint stripper and only leave it on the fiberglass for a few minutes at a time.
Be sure to have all tools and cleaning supplies handy before stripping the paint.
- Prepare the workspace Spread out a drop cloth outside or in a well-ventilated area. Paint stripper vapors can be quite toxic, so it is essential to have plenty of fresh air. Put on durable rubber gloves, goggles and a respirator mask.
- Apply the paint stripper Use a paintbrush to apply a thick coat of paint stripper over a small section of fiberglass. It is best to work in sections since the stripper should only be on the fiberglass for a short period of time before removal. Allow the paint stripper to sit for two to three minutes.
- Remove the paint Use a scraper to scrape up the softened paint from the fiberglass surface. Do this with rubber gloves and other safety gear still on. A small nylon brush or abrasive pad works well to remove paint from nooks and crannies.
- Neutralize remaining paint stripper Wipe the fiberglass surface with a cleaning pad dipped in denatured alcohol to neutralize the paint stripper. Take a clean rag and wipe the surface to remove paint and stripper until it no longer picks up color from the fiberglass surface. Use more denatured alcohol as needed.
