i have a 4' fluorescent light reflector that i'm going to cut in half and mount 2 105 watt cfl's on each one. the factory paint has turned brown and it would not clean up.i know i can get some porcelain paint to paint it with, and it would shine again. the porcelain paint is good stuff and it cost more then reg. paint. the question is should i make it gloss or should i make it flat? this setup should give me 420 watts overhead. i'm in a 2'x2'x4' box.
