Does magnesium require any special care? I know don't put water an burning magnesium, if you do spectacular things happen and they are not good.
Powdercoating specifically: pre-bake (for quite a while) to prevent outgas, as it's a very porous/outgas prone metal.
Looks like gateway powdercoating linked above has/does magnesium often (based on their site), so sure they're aware.
