Fiberglass stain remover
 

Fsr is product name. The place I get my supplies from was out of the norm so I tried this on water stain and inside mid stains. I must say I am impressed. Shake well wipe on rinse off. Immediate response.

You can also use "the works" toilet bowl cleaner. It's about $.89 cents a jug and it'll take off the worst stains. Just don't get it on your motor

Do I hear the voice of experience speaking? :p

I may try that on rust stains. Reall only thing it don't get off

Lol. Lets just say it'll jerk the paint right off.

LOL,

Sorry to hear that! LOL

I just finished doing my whole boat with starbrite hull cleaner. I did not reed the warning lables before I used it. It took the stains off the boat and skin off of my hands. WEAR GLOVES WHEN USING STARBRITE

Wear glove with the works also. Has same stuff in it just a lot cheaper at the dollar store

Yea that fsr is the real deal! Just did our triton, amazing on water stains. Not so good on scuff marks and road tar tho.

also dont get it on trailer that acid eats it

Try whink liquid in a brown bottle at walmart. Just pour a little on and the stain basically disappears. Then rinse well.

Be careful with the starbrite and other cleaners with the harsh chemicals, they also remove the gel coat. I use high gloss gel coat compound to remove the stains and oxidation then use rejex sealant instead of wax. The compounding is more work but much better for the gel coat and the rejex is better than wax and easier to apply in my opinion.
