Re: Is spraying the toons with poly urethane, after cleaning,a good idea ?

Really?? then why does my 08 Crestliner 2835 24 ft w/ 27 inch toons have half of the toons painted and the other (water half) not painted?? I think you can powder coat alloy but maybe not "paint" with the normal procedures,,We used Sharkyde at work for a whiie and it is a good product, just watch your fenders as they will rub through the sharkhyde and leave bare tube.
Paint doesn't stick to aluminum so no on the polyurathane.
