I am wondering about humidity levels when spraying clear gloss coat aerosol nitro lacquer. I live in Illinois near Chicago where humidity levels usually hang out near 70%-75%. I am reading that you need to spray in low humidity levels to avoid "blushing", but how low is low enough? Today, for instance, it is in the mid 70's, and the humidity level is around 75%; is this ok to spray? I'm seeing posts that say anything under 80% is fine, others saying wait until it's at 50%. Low humidity levels are hard to come by around here. Some threads have recommended using thinners or other additives for spraying clear coats in humid climates, but since I am using an aerosol nitro lacquer I cannot add anything to aid this process. Is blushing really that easy to come about? Is it difficult to correct? I really want to get a nice finish, but I am impatient and would like to keep working if I can. Any advice you finishers could provide would be greatly appreciated.
