Re: Need help bottom cleaning
Welcome to the forum!
Easiest way is with a paint stripper. My preference is a product called Aqua Strip (water based). Works pretty well. For the amount of bottom paint you have, it will take it right off. Apply with a disposable brush and let sit overnight (10 hours or so). Lay some plastic sheeting on the ground and go at it with a putty knife. Cleanup and rinse the hull of whatever is left (a scrub brush works well). Sand whatever is left (80 grit) and the hull will be clean as a whistle for repairs and re-coating of paint.
Bottom jobs are MESSY. There's no way around that one. Whenever you're sanding this stuff, make sure to wear a respirator (not the paper kind, but a good respirator), a tyvek suit and rubber gloves (goggles are good as well). If you can post some pics of the gel chips, etc we can give our $.02
Good luck!
[[/ATTACH][/ATTACH] Hi everyone, My first time. I got a 1987 sunbird corsair. It has been sitting for about 4yrs. I been cleaning the bottom with muriatic acid. This stuff doesn't want to come off. It looks like a blue green and the gel coat has chips and deep scratches clear to the fiberglass. I need some on how to get it off and to fix the gel coat.
Regardless of how you decide to go, continue to post pics on the progress and you will find alot of people willing to weigh in and offer guidance.
