Bottom Painting for a Trailered Boat

[CaptErich]

Hello All:
Its been a while since I've posted here. I may have already asked about this, but I don't remember.
I want to paint the bottom of my (Trailered) 22 ft boat, the color blue.
I can't use a single part polyurethane, because its not compatible to constant immersion, even for just a day or so. (It comes off).
I thought about using a 2 part Polyurethane like "Perfection", but Interlux says do not use below the waterline.
Then Woodonglass suggested Tractor paint (Majic's from Tractor Supply) using the optional hardener with it.
I'd like to hear any recommendations you have, I don't need an anti fouling paint, just a tough enamel finish that will hold up on the trailer bunks and immersion without being in long enough to foul.

to your boat, I would not bother bottom painting unless you plan on keeping in the water. at that point, I would use bottom paint.

I had a similar but different problem on my last boat.

Boat had bottom paint when I bought it. Went back and forth to remove or not and decided to clean up (sand) any rough spots and applied 2 coats of Interlux BottomKote ACT over top.

Worked great. If I dinged up the paint or showed signs of "wear", I simply used water and a scotch-brite pad to "freshen" things up a bit.

Going on 5 years when I sold the boat and the bottom still looked good. The guy that bought it from me thought I put fresh bottom paint on to sell it.

Interlux Brightside is a one part polyurethane paint suitable for the bottom of a trailered boat. You would need to leave it in the water for a few days before it would fail.

Interlux Perfection is a 2 part polyurethane paint, suitable for below the waterline.

Not sure where you get your info....

Interlux Brightside (single part) is what I have on it now. Its flaking off in a number of places. My buddy's boat has it too, and its coming off in freshwater. I use Interlux Perfection on the Hull and Topsides. This is a very tough, abrasion resistant paint. I'm considering it for the bottom as I believe it will hold up better if the boat sits in the water for 2-3 days at a time.
My info is from the Interlux Paint Guide
