Yikes,
The alternator, timing chain and starter covers along with the valve covers, heads, cylinders, and fork sliders were blasted with glass beads giving them a metallic finish. To maintain the finish I had the fork sliders, alternator and valve covers powder coated with a metallic aluminum finish. The timing chain and starter covers were powder coated a gloss black. I did not powder coat the heads or cylinders due to concerns about heat transfer and therefore over time they will oxidize and need to be blasted again. I cleaned the engine and trans bodies with Simple Green and Aluminum Jelly using SS and bronze brushes. The Aluminum Jelly is made by Duro and I found it at an Ace Hardware. Need to follow the directions, if left on too long it will turn the surface dark. Although the pictures don't show it the engine and especially the trans still have discoloration.
Probably more information than you wanted.
