I have read quite a bit on here about anodizing and cant really seem to come to an understanding of it. I have a 2000 kx 125 I'm currently completely rebuilding. I just scored a new swing arm off eBay because the current one is trashed. I plan to get my frame powder coated black because it's steel. I want to get the swing arm hard anodized black. There are no anodizing shops near me where I live. I called one that does anodizing in Green Bay Wisconsin and they said they woukd be happy to do it if I send it in. They asked me if it's aluminum and told me that is has to be sand blasted and completely stripped of any steel. I have read on here that sometimes if the aluminum is cast it messes up the anodizing process. So my question is, is a stock 2000 kx 125 swing arm cast aluminum? Can you anodized cast aluminum? Other than the chain tension bolts is any other part of the swing arm steel? Will this &%$#@! me and I'll lose 100 bucks on the swing arm I just bought? Please let me know if you have any experience with this stuff.
