Thank you all, for your replies. The home-made powder coating setup is intriguing, but I think I'll keep it simple and go as follows:
Aluminum: Alumiprep treatment. Dry well. Followed promptly by zinc chromate. Steel: Clean well with acetone, then soap and water, then flush with lots of water, then dry, followed promptly by zinc chromate. It also appears I can use paint directly on zinc chromate if I wanted to. If this approach sounds problematic, please let me know. Again, thanks for your help! -Seth On 12/26/2011 1:32 PM, Dave_A wrote: > Alodyne works for aluminum.... > > epoxy primer or zinc-chromate will work for both. > > On 12/26/2011 10:38 PM, Dave McCauley wrote:
