tooling surface question for making flat carbon panels using RTM
(OP)
How can i get a smooth consistent finish on a carbon panel surface without the odd pits and squigles i get using celophane? I have also use Air Tech's Strechlon as a barrier between my bagging layer and the glass panel i use for tooling, however pulling that off the cured panel before heat curing is easier said than done.
I am about to try using some sheet rubber since it has a consistent surface finish and releases fairly easily. Any help or input is greatly appreciated!

Have you tried PVA. Poly Vinyl Alcohol sheet? It is a little stretchier than cellophane.

The stuff you find at Home Depot is polyethylene sheet. which may work but I would not guarantee it.
The material I am referring to is bagging film from a Fiberglass molding supply house.

RTM has this problem while vacuum-baging does not.

I was looking for a consistent surface texture. Thanks again for the suggestions!
