Getting the curve out of masonite
I have some primed masonite that I want to use for painting. One has a slight curavture to it in the middle that I would like to get rid of. Drilling through it is not an option; could glue it down on wood supports in the back, but that will add bulk and weight. I also wonder that if/when it is frame that this process will handle that.
Anyone have a trick for this?
