That is a beautiful semi gloss finish😍 I should have been more specific, the metallic finish of my inquiry was on the silver radiator fin things middle of the boosters. For sure I am staying away from applying matte coat as it will pretty much flatten metallic feel and make it look grey almost, done it before swore I’d never do it again. 🤣 As for what @David Hingtgen mentioned, durability could be an issue however if you clean it well oil free prior to top coat, it should be okay?!
