Cost of a single-color paint job?

So you are going to do all this work to paint your car then use Nason single stage metallic?

Spending $126 to have someone kick you in the balls would be a better investment.

I know you want to save some money but please buy a better paint.

Tell me what's wrong with Nason?
I could get Centari as well, but I didn't price it out.
I've shot a lot of Centari and found it to be pretty durable paint. I know nothing about Nason paint other than it's a DuPont product. So, school me.
