Best way to prep rallye wheels for paint?

When I did mine, We didnt even break them down, I duct taped the tires and valve stems, my friend had a sand blaster at his garage, I took them around the side of the building, blasted them, blew them off, wiped them down with laquer thinner and let them dry.. hit them with primer and 3 coats of rattle can 'cast coat' and that was that.. they came out nice..
