I picked up some dichloromethane (weld on 3, I guess?) to glue up some layers of acrylic. It seems to work well, except I layed up on some cardboard and, of course, some drips got underneath everything and stuck to the cardboard. I think I’ll be able to buff or burnish off the cardboard this time but for future reference:
What surface should I be working on that won’t get stuck to my pieces?
