I am looking at the TDS for Wanda paint. It says flash coat between coats is 5-10 minutes which I understand. Then it says Flash Before Clearcoat 15-20mins. So after 15mins of base drying it must be cleared? I am trying to use the same gun so it has to be cleaned etc. I am just trying to figure out how much I can do at one time..I assumed there was a much bigger window between base and clear, maybe I was wrong. thanks
