glass mat, I’ve found, is a little easier to work with than glass weave or CF weave, depending on what the project is. of course, you prime and paint on mat (and typically glass weave too, although I’ve seen nice unpainted weave with tinted resins before too).
got to hand it to that guy though, that’s some tricky shit and the skill is only acheived by fucking a lot of shit square up. but nice hand-laid CF weave is always a treat to look at, so long as it’s not a wing or fenders or something that needs paint.
