talk about worrying we used to paint in a big shop with a big barrel stove we had that fire just cranking to get it warm inuff to paint as it died down we would spray the car the paint was always smooth on the woodstove side but a little orange peeled on the cold side i was always nervise about the stove but the old guy said hed done it that way for years and vents we didnt have any guess the overspray just stayed in the shop
