Re: waxing new paint
I can't speak for boats specifically, but a friend of mine runs a very good car body shop and he always said to wait at least a month for the finish to cure completely except for the catalyzed finishes. I have repainted a few vehicles and always stuck to the 1-month rule. If you wax too soon, the wax will contaminate the paint and you may end up with a "whitish" haze that probably won't come off.
