Dave,
If you want to have some fun with this you need to change identities from hobbyist to professional builder. Fortunately this only takes a second - just think up a cool name for your 'company' and start using it in e-mails. Although I'm a backyard builder, I assumed the name 'Advanced Marine Composites'. All of a sudden material vendors were lined up at my door.
If you follow this advice and e-mail Airtech International and ask tem what vaccum bagging consumables they have avaiable, you will recieve a 3 ring binder 4 inches thick with samples and technical info on everything imaginable. hope this helps,
Kevin
