So I never really believed in primer. I always thought it was a waste of money, if you sand a surface properly you shouldn't need primer. Turns out, unless you sand perfectly you'll never get a good surface. So after seeing how great the goonies cabinet looked after priming, I decided to spend the $6 on a pint. I'll be damned if it doesn't make a difference. It really helps level out the surface, and you can see how much more the cabinet sheens. Granted I only have 1 coat on, it's already obvious how much better this cabinet is going to turn out.
Also got my new aluminum angle and made another bracket, I think it will work quite fine. I should be able to adjust the mounting screws while the switch is still mounted.
