R32 Skyline winter build-up

Well while we’re sitting around waiting for parts and a slot to screw this thing together I have a question of you lot-
Powder coating wheels, I want to get the old rims powder coated black and put the drag radials on them, the question is which black- flat, satin or gloss??
Being and old shiny Centerline drag racer sort of guy black rims are a mystery to me- you thoughts please…
