Something to remember, even though you are protecting all the exterior surfaces there are surfaces that you can not get to to reapply whatever external oils etc you are applying. A good example is the area between the wheel beads that are covered by the tire, unless you remove the tires.
That being said there is nobody that is more versed in magnesium wheels than hot rodders, here is an article written by them.....
Gibbs Brand penetrant |
I'd never heard of Gibbs before. The advertisement is pretty compelling (almost too-good-to-be true infomercial good). I don't have a lot of magnesium parts, but it seems this could be pretty good for aluminum too? Makes the chemist in me curious what's in it!
