I am not that good and
I sanded and painted the metal frame of my dash,....
76 j-10 that gets pad on top, so only a few metal areas show,....
but if you are using satin or flat for less glare
( supposing yours does not get a pad )
the satin and especially flats are much more forgiving
I stripped mine
primed with rustoleum automotive spray can primer
sanded, painted with krylon satin black and it came out good
in my opinion,...
although I did have to sand it down one more time and re spray
since I had a sag that I knew would bother me.
if I can do it, you can do it. ( I am too dumb to post photos )
