i was thinkin about the bps paint also, i'm wantin to go flat black. how much does the hardner "enhance " the shine ? wonder what it would do to flat black? our local tsc store is limited in colors as far as the black goes .they had gloss and low gloss but no flat.i bought a spray can of their low gloss to do some small parts but it was a litt shiny for my taste. now as far as the hardner goes it said on the can for oil base enamels wonder if this stuff would work with rustoleum? ........dave
