Some paint questions for the guys who know paint

I'm using PPG and SPI Universal clear. I think that Summit Racing paint is bottom of the barrel paint. I may even be Kirker brand paint that has been relabeled. Not the greatest stuff on the market and is probably not a high solids paint which is why its cheap. Poor coverage with darker metallics and you'll need twice what you think. Personally I would save my duckets and get a better quality paint. It will show the difference even if you are a pro painter. Try Transtar. They are priced good for a better quality paint.
