I have 3 sets of Valve Covers that I am going to repaint. (2 sell and one keeper).

I soaked them in degreaser so the business side is very clean.
I have access to a Media Blaster (glass beads) and I will seal them up so no debris will get inside (1/4 inch plywood cut to fit the opening with a gasket).

Or should I break out the sandpaper and elbow grease?
