I was going to put up FRP on a 6 bay ss with painted cinder block walls, but with the economy tanking, I decided to repaint instead. However, this time I used the top self priming semi-gloss latex paints from six different companies; a different one for each bay (all white). Each bay was prepared by blasting off the old loose paint with a zero degree rotating tip, then acid washed, then sprayed with a jomax/bleach solution and finally rinsed and dried prior to painting. In a year or two I should know which paint is the best. I'd be happy to give updates or provide details if there is any interest.
