BAKE THE PAINT For anyone interested, I learned how to bake paint the easy way. Get a bicycle cardboard box and rattle can it flat black. Set the box up so that you can hang the frame set inside (make door in side of box that you can close, kinda sorta).
Now, ensuring that the box can't fall over, put it outside and let the sun bake the black box and frame inside. Really speeds up the hardening process.
