I have been using Nelson's for a while, and love it. I have not used it in large spray jobs (I don't have a sprayer." Just last month, on a joint project, the other guy got his experience buddy to spray it on. He would not let me do it cause I did not have the large sprayer work. In spite of my protests, instructions and everything else, he sprayed it on thick in one layer, just like he does with lacquer. Went on great, looked great. Now, a month later, the edges are peeling. When all esle fails, read the instrructions. This guy had never used the water based poly-u, but he had painted many, many models. I guess he was trying to show me my place when he did not follow the instructions.
The other guy put up the bucks, I put up the building experience. I guess he had the bucks to spare, but paint for a 120" B-17 ain't cheap.
