Spray Sealer
You know the stuff on TV where they make a boat out of a screen door---does it work? Is it in the stores?

The stuff "seen on TV" is usually something which has been around forever with a new spin on marketing. That "new" spray sealant is the same stuff you've been able to buy for evaporative coolers for years. Its just a rubberized aerosol spray. I'm sure it works just fine, depending on what you want it to do. I just wouldn't buy the 500 cans you'd need to seal your screen door on the bottom of your boat. Buy a better boat.
