I too was thinking about linex. I'm reastoring an old wooden drift boat and I put a gallon of a resin based /fiberglass mixture on the bottom and coated the bottom and 6 inches up the side with herculiner. it's a do it yourself bedliner product. it seems to be great.You can roll , brush or spray it on . The cost was only 80.00 plus a $20 rebate. I'd post a pic but haven't figured out how to on this site.
