Hey everyone I hope this isn't too noobish of a question, so here it goes. I'm working on my first kit and I'm using 3mm sintra. I'm wanting to make the chest piece more pronounced then the ab plates. My thought process was to glue 2 pieces of sintra together but I'm not sure what glue/adhesive to use, or if it can even b done. I don't want to have to go get 6mm sintra if I don't have to. Any thoughts or suggestions would be greatly appreciated.
