Oxidation on my gelcoat
Wondering if anyone has an expert opinion on the removal and buffing of fiberglass boats. What's the best buffing compound etc.?

Re: Oxidation on my gelcoat
You should only use the lightest compound out there first, and re apply if needed. Also, use a marine compound, the automotive ones are pretty harsh on gelcoats, so I've heard. How bad is it, and what color is your hull?
Edit: If the oxidation is really light just wax the hull, wax also has a slight bit of "grit" as well. |

Re: Oxidation on my gelcoat
The boat is solid white and the affected areas are mainly just around the gunnels. Thanks in advance.

Maybe you meant a variable speed buffer?

Re: Oxidation on my gelcoat
I used to detail boats, and used a high speed buffer to wax, I used a random orbital too, but mainly used a high speed. Yes, you can burn a stripe off with a high speed buffer, and if you really try you can burn into fiberglass, but not if you dont try. A random orbital will work OK. compound, rinse, then use a good wax. Carnubra wax does not have grit in it, cleaner wax has some fine grit. But if you use wax, yes, you can clean off oxidation. But not as well if you use compound first.

Aqua-buff, then wash, then 3M Finesse-it fine polish and then wax. All three products applied with a high speed buffer, foam and wool pads. Makita polisher/sander. 3000rpm. Orbital will not cut enough.It's good for touching the wax up. Gotta cut a layer of the gelcoat off if its chalky... Last edited by Bulit7; 03-07-2010 at 09:22 PM. |

Re: Oxidation on my gelcoat
Is it that brown crud we get or is it ashy?

Re: Oxidation on my gelcoat
Chris has got some good stuff at Crown Leisure Marine in D,Iberville.The Aqua Buff is good stuff too.Both will cake up in your non skid.Make sure the buffer is slingin the excess away from your non skid.If you need a good buffer you can borrow mine.

Re: Oxidation on my gelcoat
I used 3M Finesse-It on my Sea Ray with great results. I picked it up at Orielly's Auto paint department.
