column painter?

Cheapest: Rattlecan. Use a semi-gloss or matte black

An automotive paint finish will give you the best results - right up there with powdercoat. The potential issue with powdercoat is the fact that most of the column pieces are die-cast (pot metal). Powdercoating pot metal is iffy - even with a powder primer coat. Either it will work or it will bubble like crazy, ruining your finish. The impurities in the metal cause it.
