Magnesium

I've been told that you can't really get a good brilliance on magnesium. Anybody know anything?

Also, any reliable way to tell mag from aluminum?

Thanks.

Re: Magnesium

i am pretty sure that is right about the shine. as for testing if i remember you use vinager and it will fizz.

Re: Magnesium

you can polish magnesium and it will sign as well as any other type of metal that has been correctly polished, I do motorcycle engine covers made of mag and the trick is to glass bead it, then use a spiral sewn with white compound trying not to drag or cause too much heat.

If you say so - haven't tried any yet that I know of, but want to be ready in case.

Now, how do you tell for sure whether it is mag or aluminum? Agree with pickle?
