blotchy fibreglass

[Ausstu]

hi folks, after some thoughts of what would be the cause of the discoloration shown in photos? would a cut and polish fix it up? its a 2001 model 208 adventure.
apologies' for the size of the photo

Did you spill some type of liquid? Is the boat oxidized - if it is, it can more easily absorb stuff.

Will compounding clean it up? Probably. But there's only one way to know for sure now, isn't there? :roll:

Try Collonite fiberglass cleaner. It's not too aggressive. Your glass has been stained by something. Using a cleaner with bleach and leaving it on can do that.
If the cleaner doesn't work move up to a polish/compound. Keep trying with more aggressive compounds. If it does clean up, apply a good wax.
Some may suggest the Magic Eraser. They can be too aggressive even though they don't look it. It is a last resort for me.
Looking at the pics again, the stain may be wax yellowing. Try some dewaxer, and see if the stain is in the wax.

Collinite is a great product line. Excellent customer service, too. TOTALLY agree in regards to the Magic Eraser... there's no "magic" there!

You might even try a diluted water:bleach mixture (5:1, 10:1, for example) and spray it on. Spray it on, walk away for about 5 minutes, then come back and hose off. I use that quite often on gelcoat of various boats that I'm cleaning to get mold/mildew/leaf stains off. That one is "almost" magic :mrgreen:

To me, that looks like the reaction my boat's gelcoat has when someone sprays on their sunscreen / suntan lotion. It also happens when they have it on and sit somewhere or rest arm, whatever. I presume you've already ruled that out? (It always dissipates, but it is annoying.) There was also a company's marine wax product that did something similar. Really ticked me off, don't recall whos it was and have thrown it away.

I recommend you try Seapower Marine cleaner and wax. That stuff is amazing. I have used it for years with good results on red wine stains, rust stains, suntan lotion stains, and bird poop stains.

^^^ This Collonite 920 is stuff you want. Use a random orbital buffer to apply and then wipe off by hand. Follow up with a good Marine wax. I like Meguiars Marine liquid in the black bottle. Very easy on and off. Need to do this every year to get the light oxidation off. For the non-skid you can use Woody Wax.

Ditto on Woody wax for the non skid but beware! When first applied and still wet, it is anything other than non-skid. I mean super slick

looks like sunscreen residue to me too. If you are doing your spring cleaning a good cleaner or cleaner wax should clean it right up.

I try on/off or maybe some muriatic acid if it's a stain , if it's wax build up use acetone.
