I am looking to be "overprotective" when it comes to preventing corrosion but I also don't want to get involved with high power hazmat products containing chromium. So the search begins...
After looking through the forum I ran across a previous post talking about DuPont's Corlar 13570S, a chromate free 2 part epoxy based primer. Seems to me a huge benefit, not only will it seal the interior from moisture, dirt, and other corrosion inducers, but it would do so without the carcinogen issue.
So if a chromate free primer is used, what about pretreatment. I also came across a 2003 study on non-chromate aluminum pretreatments.

Based on this study, I was wondering if anyone has tried Alodine 5700 or a similar chromate free as a pretreatment before using an epoxy primer?
Again I am just in the initial planning sessions so I haven't even decided if I am going to go the epoxy primer route. That being said, please, let's not make this a debate on whether to prime or to use self-etching primers. Let's try to stay focused on chromate free pretreatments and primers, their use and any information you may have on corrosion protection.
