This is a little different answer to your original question ,while the bead blasted look is fine and a good look and pretty painless to achieve....

The jet hot is a great option at higher price ,but pretty bulletproof...

I would polish it while you have it off......some sand paper and a little polish will give it a look no other method can match...just be shure to clean and wax it real good before reinstalling it,that will make the shine last longer.

Nothing like the gleam of polished aluminum to brighten the engine up!
