Summit paint

We tried a Summit single stage, non-metallic. It comes pre-reduced (and pretty runny). The stuff laid out and cured nice but the color was so translucent there were some mismatches shooting (in pieces) over gray sealer. Might have gotten away with it over white. Additional coats would have worked too but then that's more material. In the end we recoated with a different base/clear. Don't think I'd use it again on something I really cared about.

I'd use base/clear if doing a metallic. Easier to work with, you can cut and buff, and easier to repair later.

(Before the respray I had a friend involved who was a very experienced painter in a production environment. He managed to get a lot of runs in it).
I had the same experience with their bright aqua pearl single stage. A high metallic/pearl color and 3 coats later still not fully covered. I didn't run the piss out of it but it begged to be pounded on trying to get coverage. My saving grace it was a cab and box being painted separately so not a big deal waiting for more materials and got lucky on the color match with 2 different batch #'s. I got through it just fine but with the lack of coverage, fighting mottle and doing drop coats I consumed 1.5 gal of color doing a short bed chevy not doing jambs or inside the box.
