I would also say gunked up Frank? My basement is pretty chilly and I was down there painting a few and I have no trouble with the paint being cold? Soak your airbrush in the cleaning mix for 30-60 minutes after use Frank and then rinse it out and blow some air through it and dry it out after use. It works for me!
I did clean it pretty thoroughly. I don't have any createx cleaning solution. Is their something that can be substituted, acetone or something else. I left the paint upstairs where it is very warm, wood stove, so I'll be trying again later.
