Anyone used this for fiberglass boats?

I've picked up a 20+ year old boat, with lots of oxidation, which I
unfortunately love. I've dubbed it "retrogrouch". I'm looking to do
some restoration it with this stuff.

I haven't used that, but have used 3M rubbing compound to clean up and
wax my kayak's gelcoat. I can't find the same stuff on that web site, but
it's still in the stores. It's a combination rubbing compound and wax. It'll
strip off the oxidation and add a wax coat at the same time. I think that
would be better than a cleaner.

Check your local marine supply shop.
