I am looking for info and tips on coating my Aire raft with the maravia urethane offered thru cascade. My Aire raft has a few rub spots from friction cause by over night parking in current and rubbing on rocks. I spoke to air and was told the maravia urethane would be my best bet to make my boat more durable. My question is has anyone done this how did you apply it roller, brush, spray, he long do you wait in between coats and were you satisfied with the end result. Thanks again for any tips.
