Thanks for the info... I thought I might have gone to far with the 7XXX Al, but wasn't sure.

Forgot to measure the parts prior to anodizing so I missed being able to collect that data, unfortunately.

Its been tough getting real insight into the Type III stuff as most sites etc just say, low temperatures and give very broad ranges for volts or current density. Mainly it seems to be limited to commercial operations.

Most commercial operations run Type II at 24-40 ASF (typical range I've seen). But I thought I might be able to run it slower/lower sort of an LCD Type III, just like the Caswell system does for Type II.

I guess I'll just have to do some more testing and see what happens.

(FWIW if people are looking for an easy way to strip parts, TSP (trisodium phosphate) reacts to form NaOH and strips Aluminum anodizing if people are looking for "home brew" stripper or can't get Sodium hydroxide itself. TSP is readily available at most hardware/DIY stores in the paint department.)
