I am Sooooo Confused over Paint

I'm a fan of epoxy primer, high build sandable, polyurethane single stage. I like PPG concept but our local vendor is dropping it, says it's too expensive. I'm bummed because I have a half gallon of color left from my Barracuda build and the rest and have a comet cyclone to paint that codes out red on white and I am thinking about painting the car the same color as my Barracuda.
