If you have a good auto paint supplies store they should have what you need-
Alumiprep (etch)
Alodine 1101 or 1201 after you have etched and rinsed thoroughly. (1101 is clear, 1201 gold tint alodine)
Dow, 3M, Henkel Surface Technologies are all mfg.s of these products. Same stuff we use in aviation for corrosion treatment of aluminum structures and parts. Follow the instructions on the containers carefully.
Muriatic can physically eat away at the grain structure of aluminum alloys, even when diluted greatly. Stick with the Mil-Spec stuff......

i used to use lime away and a hard scrub brush...my driver phil would make fun of me...so he made a point o bring me a ultra soft brush, 1/2 gal of water with a cap of ma in it....the **** falls off!!! i felt like an ass!...after that we rinse everything and spray and whipe clean with royal purple spray. the inside hub on all of our props look better now that when they came out of the box.
it will burn like hell if you get it in a cut...and eat holes in your clothes...

What about boiling out the innards of a procharger intercooler? What would you recommend to eat the salty crap out of them and THEN what would you recommend to run back thru them to kind of leave a protectant there (no more salt thru them, only fresh from now on).

bro...i have no idea what lies in that intercooler...or what coating(s) they may have used....i do know we flush with fresh water and dish soap does a damn good job on our engines...what does procharger say???
we have propblems in dyno testing with coolers...our water is hard on them....we now replace them at a given point no matter what.
