I have been painting my 83 Buick Regal which was originally burgandy and i started painting it gloss black because i couldn't find anything in rustoleum that was a dark enough red. I had the car painted 90% black when i decided to change to gloss white instead and now it's completely covered and i've only used 1 and 1/3 quarts of paint,i do intend to use the rest of the second quart though before doing the final wet sanding and polishing.I've never done very much roller painting before but this has turned out excellent.All i can say is if you're wanting to try this technique,read and follow as closely to 69charger's procedure as you can and it will come out looking .
