Yes I do own vac-bag material of a few types, two pumps and all the stuff to do vac- bag lay-ups. What I would really love to own, is an autoclave. Though I do have access to two of them. To do the snorkel scoops using the vac-bag system isn't cost effective for me. It's great technology, but over-kill for the part. I use a wet lay-up with vinylester resin that takes thirty minutes, thirty minutes to demold, bond the inner tube in, trim and done! I was comparing the weight and cost of a NASCAR hood today using a regular glass lay-up, light wieght S2 glass/epoxy resin system and corbon/epoxy lay-up. The carbon hood was three times the price for a wieght savings of about ten onces. Maybe that's enough to win races! I don;t know, but seems like a wast of money to me.
