As a few of you know, I am in the middle of building my 29mm CF scratch build (video build). I have my mandrel and made the fiberglass part of the tube last night. I wrapped the tube in this plastic stuff i found and prayed that the glass would slip off. I know, BAD IDEA. The tube isnt coming off and I'm afraid that Ive ruined my mandrel.
Here's my question: what plastic easily peels off of fiberglass? In the past I have used ziploc bags (which actually work great for making fiberglass sheets) and wax paper (which didnt work at all ) It needs to not scrunch up like plastic wrap, but NOT to thick that it wont wrap well. I have heard the Mylar works perfectly for the job but the only place i know that sells mylar (PET) film is McMaster-Carr and I would rather not pay shipping. Does anyone know of something that i could pick up at home depot or ace that would work equally well?
BTW: My mandrel is wooden so using a mold release would be out of the equation.
