Awesome Brian!
However, I just read some disheartening info on this web site:
http://www.focuser.com/anodize.html
Here's a quote from the site,
"Note: if the aluminum part has other metal or steel parts pressed into it, do not re-anodize the part. Metals other than aluminum will dissolve away during the anodizing process."
Glow engine heads have threaded glow plug inserts. So, if I try to re-anodize my old OS Max Goldhead, or my Webra Blackhead, I will probably damage the threaded inserts. Bummer.
