I don't suggest attempting to coat the inside. It's too difficult to prepare the magnesium for good adhesion, and I don't see coating the inside as being successful long term even if you were able to get the surface perfect. The original coating is a two part high temp ceramic coating so that would be my first choice (I use Cerakote), although PC works well when well prepped. The factory didn't fully coat the inside. There is overspray inside, which is what flakes off first.
