I never said it's gonna take a whole gallon to paint my car. I'm not a body man (hence the reason I'm not doing it myself...) but I understand it takes about 3 qts to do a good job on a car. Doing simple math to extrapolate the price of a gallon of red paint based on a pint of black is ludicrous. Red is by far the most expensive color. There are so many different brand and styles of paint that that comparison is meaningless.
I just pulled out a paint estimate from a year ago from a different shop, this was DuPont paint which is comparable to PPG which is what my shop is using. The base red paint was $136/qt and the clear was about half that.
I've been thinking about painting this thing for a couple years now, so I've read tons of article and forums about it. I've seen the famous "$100 paint jobs" and the orange beetle, and the orange charger, and all those. Seen a couple guys who did them to their car too, and it looks great from a small distance and it's certainly better than rust or multi-colored cars, but up close you can just tell it's not a professional job. I wanted something I could wax, be proud of, take to local shows, etc etc.
