Very helpful post, thank you.I would have gone with a hard paint if I had thought ahead enough to know I'd eventually have to put the boat on a trailer occasionally.....
I share the same sentiment on bottom paining; basically, a necessary evil in our situation.
Our dealer (in NJ) uses a primer and hard (epoxy?) paint as a base/first layers, thereafter ablatives as necessary down the road.
I have a strong preference for bunk trailers as we often trailer pretty far. Hoping the good maintenance of bunk cover and the initial hard paint would work okay.
