RE: Peel Ply techniques
I re use the perforated peel ply all the time. The only thing I use it for is when I layup a part in a female mold that I intend to vacumm bag. AFter I am done laying it up, I put the peel ply down on the resin/glass and then a layer of good quality paper towels to soak up the excess resin that comes through the perforated holes when I apply vacumm.
Works good and removes excess weight.
