No I have not done any buffing.
first I painted it with auto body primer filler, a lite sanding with 220 repeat 2-3 times then paint with high gloss black let it Dry then paint with Rust-Oleum Bright coat Metallic finish thin coats. wait about a minute between coats (and don't touch it for at least a day ) this is what I did.
if someone knows a better process please post.
