Both are PPG products. I'm sure there are similar products in other brands that would do the exact same. I use PPG because that's what I learned with. Please note that it will not be anywhere near as cheap as the farm stuff, but it will last for many years looking as good then as today. What costs more, paying a chunk for paint that keeps your ride the way you like it, or doing cheaper now but repeating several times.

Bottom line, what's more fun, painting or driving?

Check around for an auto paint supplier in your area. If you cant find ppg, try one of the other better brands.
