Hi Marvel folks. I got a White Sheep Leather Endgame suit without chest scales, and the HurleyFX scales kit. I'm trying to figure out how to attach them with regard to the collar snap buttons. I've heard the thing to do is punch a hole in the top urethane pieces for the snap to go through, but the urethane seems to be a bit thick for that. That is, I can sort of get the button to press in, but it's not strong enough and pops right back out. Should I instead be trimming around the area? Or am I missing something else here?
