Hello! This is my first time here. I've found the tutorials very helpful in building my first helmet. I have limited workshop tools; I don't use power tools so I put the helmet together with a strong pair of scissors, screws, a hard hat, bucket and spray paint. One problem I kept running into was the visor. I couldn't find any workable material and ended up with soda bottles.... The first attempt was ok but see through. I found a tinted one for my second attempt, but it buckled when hot glue was applied. My question is, what is a good visor material which will hold up under the glue gun (and that I won't need a saw to cut)? Thank you!
