refurbishing magnesium wheels
Just a note of caution about genuine old magnesium alloy wheels. If they were originally treated with a Dow process(usually looks greenish underneath the top paint coat) then they will dangerously corrode if you blast or strip or otherwise remove the passivation layer. And it'll happen under your shiny new paint so you won't see it. This is the case on old Ferrari Cromodoras.
here's a quote about Ferrari Dino Cromodoras from the Dino site I belong to: "Noooooooooooooooooooo!
"Blast cabinet"
No no no.
Dearly protect the DOW 17 (greenish coating).
Research Mil-M-45202 protective coating for magnesium. Very expensive to do correctly. You can call General Magnaplate, or TAGnite. Big undertaking. Chemicals used are vicious. DOW 7 & DOW 9 are not the same level of coating. DOW 17 is a military quality coating for Mg that revolutionized use of Mg for automobiles. Before that, it was watch them disintegrate."
A lot of wheels are colloquially called "mags" though - and this may not apply to them.
