Same issue, i have cracked paint, i have air bubbles in the paint thats not cracked and i have rust around some of the welds. I went the AWS and SC trying to get them to push on Boat Mate and no go.

Basically the only warranty you get with paint is if its chipping off when you buy the trailer.

Other then that parts are warrantied for 1 year but its Parts not labor. When i buy my next boat i will be much more aware of the trailer and what type i can get or will get.
