Stains on fiberglass seats

238 Views 8 Replies 7 Participants Last post by  pdqaltair
A can of Hellmans spar urethane leaked onto our boat seats. We have tried Klean Strip paint solvent, 100 acetone and a stripper. Did not move the stain. Any advice on how to clean this?

Dental pick. Reach in the diamond pattern with a sharp tool and flick the varnish off. If that doesn't work try CitriStrip available from the big box stores. Smells good enough to drink but don't do that.
If it鈥檚 anything like varnish on exterior, teak, it鈥檒l peel off in no time!

[/QUOTEI鈥檓 not sure where you may get it, but I read that methylene chloride may do it
Methylene chloride?
Indeed, is it remnant varnish? Or a stain left on after the varnish has been removed? i.e. the colour tint in the varnish.
If its just the stain then Muraic Acid could work too. Paint it on, leave for 30 seconds and use a lot of water to remove every trace. If it doesn't work try again for a little longer.
Methylene chloride?
Will remove the gelcoat.
I'd either ignor it or try a heat gun and a brass or stainless brush. The heat will soften the varnish before the gelcoat. Watch the heat and start in a corner (I have done this with epoxy drips--it worked better than anything else).

Also oven cleaner (caustic based paint stripper). Let it sit and then brass or stainless brush. Won't work in epoxy, but works on some paints.
