At what temp should you worry about youre paints,glues and any other modeling supplies ruining. Which paints withstand cold better acrylic or enamel.

don't know exactly, but figure if you can't stand the temp, either can they. I wouldn't want to get below 50 F or more than 110F. they probably can deal with more extreme, but hey, it ain't cheap replacing 30 -50 new colors if you are wrong

For storage, I would just make sure nothing freezes. For use, above 60 degrees F should be fine.

Ive managed to store my paint in areas as low as 20 degrees celsius and still remained usable.

If i was to store paints for a longer period of time, i would place them in the hot water cupboard which some houses have. The temperature in there is usually in the high 20s to early 30s (degree celsius)

Thanks guys it very seldome gets below 20 were I live. But I only have an electric heater to warm my hobby shop. I am afraid to leave it on because of fire hazzard so I moved all my paint in to the house which is kind of unhandy but its better than losing all my paint.
