How to protect new deck from rotting?
I will be purchasing marine grade plywood tomorrow to replace the deck on the new-to-me 1985 16' Mirrocraft aluminum fishing boat. My original plan was several coats of oil based spar urethane, with the topside painted with Total Boat TotalTread. But after some more reading I'm having second thoughts. Keep in mind I'm trying to do this on a family tight budget around $100 for the supplies preferably. I already got a quart of TotalTread so I'm sort of married to that as the paint of choice. What would you guys recommend?
