HELP WITH PAINTING ALUMINUM TRIM ON IMPALA

I was wanting to know how to prep and if i should use a primer, sealer, before painting.  I will be painting the strip on the side of the car, not the whole trim itself but just a strip. Any advice would be greatly appreciated. Thanks Josh

I would scuff it real good with a grey scotch brite pad. clean it with windex.  spray a few lights coats of adhesion promoter (bulldog) before spraying paint.  you should be fine with that i dont think you would need primer or sealer.  kinda hard to say more than that without seein it. put a pic up.

sand it good with 320, etch prime then sealer then base/clear.

and I might aswell add my opinion too.....sand with 220/320, clean with degreaser, epoxy prime, then paint. Epoxys are better for aluminum because they dont contain phosphoric acid that can damage aluminum.

hmm we always use spray bomb 1k etching primer from dupont.
