Grit blast the parts with #100 to #120 grit aluminum oxide or garnet sand at 80 to 100 psi. Lightly blast (30-40 psi) non-metal parts such as: wood, fiberglass, plastic or polymer. For anodized aluminum parts, set the blasting pressure to 30-40 psi. Strive for an even blast pattern over the surface of the part.

This is good.  Make sure and research the media you're using.  They're not all the same.  120 grit aluminum oxide is my preference.
