I'm finishing some furniture in my garage because I don't have an air conditioned spray booth or workshop. Since I'm in Austin and it's summer, it's hot and high humidity. I have tried using retarder and thinner and working first thing in morning but I can neither get it brushed on without brush marks or sprayed without orange peel. I have a turbine HVLP and even tried putting the hose in a bucket of ice water. Spraying seems to dry even faster than the brushing. I'm not sure what to try - more retarder or thinner or both, which method, another finish on top or something else? Starting to get frustrating.
