Anodizing cast aluminum
Hi,
I'm trying to anodize a cooling head for a radio controlled car engine, using my usual (successfull) process and I simply can't get a good result.
It get's chalky, it doen't take color right, it get's spotted (looks like there are air pockets or something breaking open during anodizing) etc.
The part was anodized before, so I know it's got to be possible.
Heeeeeeelp, please!!
