A while back, I was trying to find a source for Alodine solution, a treatment commonly used on aluminum to prevent corrosion in the aircraft industry.
Finally, today I stumbled on a source, the link is posted below.

Just check the "discription" button and type alodine in the search box.
The prices are a lot cheaper than I expected but I also think that this is working solution, (diluted), not a concentrate.
I would have preferred a MSDS on their product but not to be...
The reason I want this stuff is to treat newly bead blasted carburetors prior to assembly.
