I've been gone for a couple weeks, so missed this thread, but since my name came up, I thought I would give my somewhat modified opinion of Penatrol. I originally used the product when I started restoring Tullamore. She was badly oxidized, and my attempts at buffing were not very successful. I read about Penatrol on the Trailer Sailor site and gave it a try. It did give the hull a nice shine, but my prep work was not up to par and the yellow gel coat was blotchy underneath. I had 2 different professionals assure me they could buff it out and it would look great. Both were wrong. They were surprised they couldn't get the oxidation off. I began to suspect the Penatrol. After reading Scott Grometer's comments regarding the Flicka groups discussion, I'm convinced of it. This spring I wet sanded the hull to get down to good color. That did the trick, but I had to change sand paper very frequently as something was plugging it up. I had de-waxed the hull, so it must have been the Penatrol. I belive Penatrol would have been fine to use then once the hull was completely deoxidized, but I decided to try Poli-Glow. Got a great shine. The hull looks like new. I still belive Penatrol will give you a good shine, but do not apply it over oxidation, at least on colored fiberglass. The white topsides looked great with the Penatrol, but I suppose that's because the chalky oxidation was the same color and the Penatrol just made it shiny again.
