Paint your bottom for $20 !!

My 1977 10 footer has been taking on a bit of water, so over the holiday I decided to paint the bottom to seal up all the rivets. First I applied JB Weld to some knicks, then two coats of paint, all for $20. Good ole Rustoleum Metal & Aluminum primer, and an oil based (for metal) enamel in Hunter green. Two quarts and disposible brushes and had change left from a $20.00. Worked like a charm, dry as a bone now. You can spend more on paint, here is a durable, low cost alternative. Photo shows primer and the high gloss top coat. That bottom is now so slick I think I gained a knot or two in speed!

Rustoleum was the exact opposite on my boat. Used the same products as you, but once I get a scratch in it, the water got under the paint and primer and blistered really bad. Turned into a 95 dollar project really fast.

That's not good! Where I boat it will be tough to scratch but I'll be careful, thanks for the heads up!

problem is, the scratches came from trailering the boat. The stuff isnt very tough, even with 2 thin and 2 thick coats..
