I use resin as well, depending on what I want to make, but some of the alternatives do have their virtues. The nice thing about using something like Laser Bond for casting small parts is, the parts can be cast instantly. If you're in need of something "right now" you can avoid waiting for curing times & have the part in hand & ready to use in seconds. Plus, If I'm just casting a set of window cranks, It's a lot less "mess" than dealing with mixing 2 part resins & cleaning up afterwards. Steve
