Please, post pics when you are done with it. I've read the threads concerning it by Tim Ballie, and am interested on how well it works.
I'm about to use "Rigid Filler" from Dominion. I got it off one of the fabrication links hear. It was recommended by a guy named Time Basille from hzemall.com. He is supposedly some supper pro in the custom audio world. I'll tell you how it comes out next week when i get my lilliput. Supposedly a hell of lot better than bondo.
