[NRVR-Members] Glassing - Best suppliers for peel ply?

[Bob Schoner]

I have done vacuum bagging of plywood fins but before they were installed.
I used Teflon peel ply which is expensive but works really well. I did a
sandwich of plywood fiberglass peel ply and bleeder cloth. I’ve used
Fiberglast but there are other options.
