Awesome Job wood! Just watched the vid, wanted to point out the bass automatically blurrs out the cursing. What a good guy! Seriously though, awesome job. I see you glass sealed it, then primed it. What did you use for a primer? I know if you use a finish resin, it has a wax in it. The wax can make it hard to stick to. Does it seem to be sticking ok? On the inside maybe carpet would do the trick? You could carpet the whole back side of the cab and wrap it into your box?
