Not sure why since it is not engineered to work that way.
Yap, even the purposely-mixed Deltron single stage does not carry the wet look as well as hand-rubbed lacquer or even acrylic enamel, which when done well gets that "porcelain" look. But the urethanes will far outlast both of them by far. For the ultimate "euro wet look", as we used to call it, nothing beats a nice 2-stage finish.
I was never "in the business", but in my days I sure painted a lot of spoilers, side skirts, motorcycle tanks and fenders, as well as a few car overall jobs.
