Yeah I used Hot glue. I wasnt really that happy with how the back turned out. The second AO2 mask was just kinda funky looking because theres no support or anything in the back to support it, so its just kinda leaning on itself.
Well I finally got done pepping an HD helmet.

Any words of advice would be appreciated.
