I believe that Floquil RR paints are laquer. If you don't paint Floquil's Barrier over styrene and apply the paint with a brush, it will literally melt the plastic. If you shoot it on with an airbrush, it goes on well using 2 or 3 very thin coats. Just don't try to strip it off because it won't lift. Back in the '80s and early '90s FSM ran several articals on the use of Floquil RR paints on styrene models.
Several years ago Floquil released a line of enamel military colors but I don't believe that reefer white was one of the colors.
