bottom paint

[badfish88]

ok, heres the deal. i bought a 20' angler c/c last year. the previous owner had the boat bottom painted with a antifouling ablative paint. he kept it in the water all season, i trailer with every use.
The current bottom paint is peeling off all over the place and the scuffed gel coat is showing. The cost of having the bottom re gell coated is rediculous. Ive read that for a trailered boat i need an epoxy based paint, ($90+). i was thinkin after i sand the big peeling chunks off, is there any other kind of paint i can use on the bottom of my boat with a smooth surface, that will hold up to the abuse?
ive seen truck bed liner on the bottom of jon boats but i think the rough surface would kill the hull speed. Even the expensive "trailer boat paint" needs to be re-applied every season, so i figured cheap paint that will hold up to being trailered would be better. what are your thoughts........


thanks in advance
