I brought an old set of alum. wheels to a sand blasting place, cause my previous attempt with sand paper, dremel and primer didn't work. (peeled within 6 months)

They used a real fine bead and blasted everything I needed (think the size they use for glass etching). I then primed and shot with a high temp paint. I saw the car recently at a car show and the rims still look like the day I painted them.

hope it helps....
