Hi - I have some stains which appear to be petroleum based on the inside of the boat, I guess gas when it was being filled and was spilt. Looks like it dried and then stained. Any pointers on what I can use to get it off without messing up the boat ?

Maybe a stupid question but I have a large tank underneath the center seat, too large to take out to fill, other than being real careful and not having waves etc. to deal with.
I fear it may happen again - what do some of you guys do to help prevent this?

thanks !!

West MArine has a product for cleaning nonskid surfaces, it removes these stains very well, you can also try soft scrub or FSR (Fiberglass Stain Remover)

I use to use soft and scrub, did a great job. The veterans on this site said you should never use chlorine bleach products on fiberglass, it dulls the gelcoat. They say to use Bar Keepers Friend(looks like a scouring powder, same isle at Pathmark). It has the same kind of acid in it that is in hull cleaners. Two weeks ago I scrubbed my whole deck with it. It is fantastic. Did a great job. Good luck.

Does anyone know where I can get "Bar Keepers Friend" other than Pathmark - we don't have one around here ?

I tried using FSR several times yesterday and it didn't work,these stains are pretty strong I guess or FSR can't handle these types.

Anyone else got any tips ?

Hello, I'm a newbie to this forum, but have been reading lately. I am looking to buy a one owner used 1994 15'Dauntless from Twin cities Marine in TR, and the upper decks finish has been scrubbed by them with a cleaner that gave the gel a dull abrated finish. Do you think this can be waxed or buffed to a gloss again? Another item with this otherwise great boat, it exibits some small cracks coming from the screw holes by the motor controls cover on the aft floor. Is this a great concern or is it just gel coat cracking? There is also a thin gel crack (4") by the front eye. Please offer any help you can to my questions. If this does not pan out, I am going to pursue a 2003 or 2004 150 sport or a 17' Montauk. Thanks again.

If the finish of the gel coat in the non-skid areas has been abraded by sanding with course paper it will probably not be easy to restore it. If the gel coat is just dirty, dull, or oxidized in the non-skid areas, you can probably improve its appearance by using some gel coat cleaner or oxidation remover, then buffing with a fine polish like 3M-Finesse-It-II.

Small stress cracks in the gel coat layer are not unusual nor are they a cause for concern, unless excessive. Cracks that radiate from screw fasteners were probably caused by poor installation. When drilling a hole for a screw fastener through the gel coat, you must enlarge the hole in the gel coat layer so that the body of the screw has clearance. If this is not done the gel coat will likely develop a crack from the forcing of the screw into a hole that is too small. Of course, you only enlarge the hole in the thin gel coat layer, leave the laminate and backing wood with a proper size pilot hole for the self-taping screw to obtain purchase.

Thanks so much for the help. I just got back from my third inspection of the craft, and decided against the purchase. I found several other fine cracks in the bottom and the bottom 1/3 of the hull was painted whiter than the rest of the hull. The paint wrapped slightly around the stern, leaving a sort of shoddy paint job. Sooo, I walked over to the 150 sport fully loaded, gave her a tap and told AL to take the shrink wrap off and prep it. I am taking the maiden voyage on Wed.
