thx guys.
as for the prep. i just sanded them down, but not all the way so its smooth, as i liked the textured look that those pieces have, then washed them, cleaned with rubbing alcohol, then sprayed with t229 metallic silver, about 6 coats or so, then 2-3 light coats of clear coat, then when it was dry i sanded it down a little as well with 2000 grit sandpaper tog et rid of some orange peel, but there was actually none there so its all good.
here is one more from the opposite side.
