Absolutely true about the blushing. It may take awhile to show up, so be careful. I tried painting a 1:1 a long time ago with lacquer when it was around 60-65 degrees. I had to put so much retarder in the paint to avoid the blush that it took nearly a half hour to tack off. It still blushed, but man, was it smooth and shiny! I was not able to polish it out. It was a dark navy blue, so perhaps a lighter color wouldn't be as bad.
