I'm looking for opinions on which method is best for fiberglassing tubes. I have experience with using mylar film and a credit card to get a smooth surface when smoothing out epoxy on a glassed tube. Its not a perfect process as trapped air bubbles can be a bear to get out to the ends.
I've read about peel ply, some other type of impervious film with holes to allow air to escape. I have almost bought it 3X, but would like to know if its any better? Seems like its designed for use with a vacuum bag, but how does it fair when used in the manner of mylar film? Is the air easier to get out? Leave less voids on the surface that need filled? My concern is you can't see through it like Mylar so perhaps there are just as many air voids after because you cant see them.
Interested in the collective wisdom. And thanks in advance for the notion of "Just use fiberglass tube", but I have a lot of projects requiring glassed cardboard.
