cross linked polyurethanes (the one's with the 2 part additive) are very tough and extremely difficult to sand...sanding/buffing isn't recommended. You better get those right out of the gun.
Tougher than gelcoat? Don't get me wrong, I don't know everything, hence why I posted the question in the first place. I just thought Gelcoat was the hardest stuff to sand and buff in the coatings world. I was hoping this time for something that would hold a pretty good shine for a long time and would be easy to do small repairs and even relatively easy to recoat the bottom as needed. [/quote]
Yes...harder than gelcoat. When guys are refinishing boats already painted with the stuff, they try all sorts of things - even sandblasting, to remove it.
