If it's cosmetics and durability you're after, there is a SAILBOAT epoxy paint Spareparts has spoken about...leaves a good, slick surface and hard enough to resist trailer loading....hopefully he'll see this and tell us exactly what paint it is...I'm sure you know, you'll have to sand the existing bottom paint, then PRIME, then apply the finish coat...and probably at least two coats of finish coat...if yer doin' it all yourself, you got a job ahead of you...
