:smile2: I've got a 20' aluminum seaark bay style boat that came with vinyl in it that has gotten in pretty sad condition. I originally planed on installing carpet but now have decided to go with spray in liner inside and out down to corner at the bottom. I've got 3 bids and 1 said the boat would need sandblasting first in order for a proper bond. The other 2 said that the primer would be all that was needed. My question is has any one had experence with this and if so I really like to know your experience with it. Thanks for any help you can provide.
