I posted this earlier in open discussion, but it more properly belongs here, I think.
Prekote is a metal surface treatment that replaces acid washing and alodine on aluminum, and also works on mag, Ti, steel and even composites and plastics.
The claim to fame is that it's non-toxic, biodegradable and actually works BETTER than alodine. Of course it's a bit pricey at over $50/gallon. I don't work for them and have not as of yet used the product. Just looking for some users who have tried it. Seriously, the low toxicity and ease of disposal is quite attractive and would likely offset the higher direct cost-IF the product works as advertised. This looks like something we just
have to try
