I was painting yesterday in my Mum's garage. I sealed the main door with masking take to prevent drafts and to keep it warmer inside. I used several heaters on the far side of the room to keep the room between 12c and 15c. I managed to get a load of spraying done without any problems. However when I tried respraying my tailgate strip the paint kept cracking.
I would have thought the paint would only crack if it were too warm???
