How to Age a Shiny Aluminum Chassis

[scstill]

I have a Hammond aluminum chassis that is going inside a vintage cabinet.
I am looking for thoughts on how to age the chassis so that it looks vintage.

Marry it.
It'll put on some extra weight, stop caring about how it looks, and age 10X faster.

Another upside is that if you accumulate a pile of stuff, eventually it will take half.

Silvergun, that was hilarious.   Aging Alu is tough.  You can try all the standard washes/soaks like vinegar, mustard, bleach, lemon juice, etc.  I've experimented with lots of methods having built knives, a flintlock musket and effects pedals.  Muriatic acid will work but you'll need to experiment a lot.  It's mean stuff.  Ferric Chloride is reliable and controllable.  Brush or rub it on, let it sit for a short bit and rinse.  Repeat as needed.  Interesting project for sure.

just heard on radio Michigan man took some leftovers out, threw in the micro-wave, wasn't bright enough to realize that aluminum wrapped food n microwave oven don't mix, no humans damaged, excessive property damage 
I'm pretty sure I know how he voted 


I've used propane torch, muriatic n a few others, gave up and glued copper foil to the aluminum, then aged the copper

Thats a better explanation thanks. But not the look I am going for. trying to just get a uniform dull matte look. Like a guitar amp chassis that has been sitting inside the cabinet for 50years. I have successfully used vinegar and vinegar vapor to dull ferrous metals, but its not working on the aluminum. I used acetone to try to remove the hammond factory finish. Still no luck.

Tried bleach (turned brownish), tried vinegar (did nothing);
I ended up using an orbital sander with 3000 added a nice aged look
but shows fingerprints. nothing really gave the old chassis look
Next Time just going to leave it be....
Now its time to build it
