I never had a complete seat redone but you should check with your dealer for who they would recommend to do the job or call around. I've had more visits to the upholsterer than anyone else who has worked on my boat. Stuff happens and most of the time the stains and rips are out of your control. I wouldn't have expected a wetsuit to do what it did. I do know suntan lotion can stain the fabric but I'm not sure which brands they are. I know hardware on swim clothes can damaged both the fabric and scratch the jellcoat.
