Hey, I'm from France sorry for not mentionning it. Thank you for the answers, I started using some paper and glue but I think i'll do the fiberglass and resine way, I have some but it's very toxic. But for the dom, if I use fiber, will it be ok ? I mean because it's a dom form, the cloth is going to get a layer, it's going to be apparente ? I never used resine, is it going to do a big layer that I could sand, or is it going to make a small layer ? I don't want to see the fiber, I want it to be smooth, like a perfect smooth surface not ugly like cloth looking.
