: I've sprayed some boats with 303 and successfully varnished them later. As
: long as it was just 303 you used and not silicone, I would not worry about
: it. Washing the boat down with a strong cleanser and water may well be
: sufficient to get rid of any residual 303.

I don't know what's in 303, but it does repel water, and the folks at Betsie Bay had to put ENORMOUS amounts of labor and powerful solvents and other nasty chemicals to get it out of the wood so they could refinish the boat. Don't use it on wood if you might ever want to refinish or repaint it.
