I was hoping for a darkening effect to better match the Paint Color of the rest of the Plane. Will have to investigate this Birtchwood Casey Solution.

Am going to try Pool Chlorine and see the results.

Saw a recipe for a Blackening Agent on the web, I am leery about mixing chemicals, as I'm no scientist, I wish to proceed with caution.
The drain cleaner was probably acidic, hence the "white" color to the aluminum. You have to have an alkaline product or something more like the Birchwood Casey solution. The birchwood product will turn the aluminum absolutely black.
