[R-390] Anyone know where I cann get some alodining done?

Don't bother. You can do it yourself.

Get a bottle of Alodine 1201 and Alumiprep 33.
Clean the panel real well. Then clean it again with Alumiprep 33 and a 
scrubby sponge. Be sure and wear rubber gloves - the stuff is phosphoric 
acid and is quite nasty. Your alluminum will never look so shiney as when 
you finish scrubbing it in phosphoric acid. Rinse immediately with lots of 
distilled water, then paint with or dip in the Alodine for a few minutes. 
Rinse again with distilled water, let it dry out, and voila! One 
corrosion-proof finish. Watch the temperature - the solutions need to be 
room-temperature.

The problem is getting the stuff. You can get it at www.aircraftspruce.com, 
but they will hit you with a $30 or so hazardous materials charge. You can 
probably find it locally at some aircraft shop or machine shop or 
professional tool supply.

Good luck!
