I originally was going to polish my case but decided that I liked the look of ZF cases that have been glass bead blasted. I recently saw one in person and was very impressed.
Tonight I just started bead blasting mine and am a little disappointed with the final product. I like the clean satin look that the glass beads give you but the actual metal still appears wavy and slightly pitted (casting marks/ impressions).
Do most people sand their cases or wire wheel them lightly to smooth them out before glass beading them? If they do sand them what grit do they start and finish with before glass beading?
I am concerned that dirt, grease, and road oil will fill in the small indents and pits eventually and be almost impossible to clean out. Also I do not remember the wavy and slightly pitted look on the transaxle I saw in person.
If anyone has any advice or recommendations I would appreciate it. I have looked through the forum but do not see anything on the specific method of glass bead blasting. Thanks.
