Well, to my horror it seems the TTs got aluminium covers and the NAs got magnesium with a mix of alu in it NA ownership is tough
Now if mine were aluminium a good old polish, or high heat primer/base/clear would do.
But as magnesium is 'pourous' it likes to breathe gas which is why the NA valve covers always have dark spots, soaked oil. So a polish wont last and painting may be literally pushed off by escaping gasses
I really wanted to polish my spares that i just got but dosent seem worth it as it will eventually return to a grey cast finish. Has anyone ever powder coated NA cam covers? and can they really warp?
