Hey Rob,
Nice to finally meet you in person at Royal Purple. I didn't ask, but are you using my Polish currently? The water should just sheet off instead of heavy beading. I see anywhere from 5 months up just depending on length in the water, etc...
I would buff first with the OR to remove any buildup/stains then apply the Polish by hand. Give it a clean/fresh area since you're working with the bottom.
Let me know.

Try the Slimy Grimy. It really does work well.

We had an older Formula that did the same thing. A friend of ours had the same model that always maintained a white hull while mine yellowed out each time out. Asked him what they used to keep it from yellowing. It was a product called TSRW (This Stuff Really Works) Clean the hull and apply per instructions only once a year. If you miss a spot on application you will soon find it. Clean and reapply over missed area. There are some other products similar that I am not familiar with. Here is a link to a good article on some of them including TSRW. It kind of reminded me of Mop-N-Glow. ![Big Grin](/forums/images/smilies/biggrin.gif)

after your get it white again it won't be nearly as difficult of an application. my boat's bottom was tan when I bought it... just put it on thick and let it sit for a while, after that, super light coats every once in a while.

Acid tents to also open the pores in the fiber glass to alwo future build up, so put a good coat of wax or polymer polish on shortly after if you can.
Only other bit of advise is to soak the boat and trailer first with water, I hear it can eat the metal if left unrinsed for a period of time.

I have to find out the name of it but my friend turned me onto a chemical that's 100% biodegradable and does not burn... It's used to clean stains/deposits that are in pools....
