Dave, a buddy of mine sprayed Nason base and clear on my 99 Cummins that had some body damage when I got it. It sprayed pretty well but color matching by the paint codes was crap? After that experience my local O'Reilly matched the existing paint with Nason using their meter and it was a great match.
That doesn't sound like an issue for you here but keep that in mind if you consider it for future projects where trying to match.
I had this discussion earlier today. You are right, I'm not a body shop or a collision repair shop, I'm a restoration shop, I do overalls only, no partial jobs. So, matching isn't part of my deal.
If I like the way the nason sprays and finishes, I may stick with it.
