and ask for a sample of their 4 and 6 oz cloth.

do some wet out test.

Why screw around with that tight weave cloth after all that hard wordworking. Are you building a space shuttle that you are going to paint?
Newfound builds boats. The use cloth that works well for them. They do it every day. It's a more open weave and presents none of the problems that everyone's trying to figure out how to solve.

You might pay a tiny bit more but you wont be crying later.

I read all that glass strength stuff. interesting. I have built 5 strippers and none are comming apart. This is not an endorsement. It's more against tight weave cloth. I just know Newfound has a reliable product. You could certainsly get good wet-out cloth at a lot of places.

I like Larry at Raka and his epoxy. I don't like his glass or any tight weave stuff. Not for clear wet-out.
