I hate colder weather...being quite a lazy person I base coat my figures and models using Black Spray Paint. I also am a cheap bugger...hence the use of Paint from work.
Now I also use Tamyia Spray Paint as an overcoat, mainly for my Soviet Vehicles and I have found that this stuff generally works well even into the depths of Winter, However my base Paint hates the cold and will flake off if you don't judge the temperature right.
Here's some examples of that on my Soviet ZIS 3 Guncrew.
Being the fool that I am I continued to paint over the figures in the hope that the enamel would bond the flaking...fat chance, perhaps the only way out of this is to carry out a PVA glue dip then carry on the painting with the PVA acting as a protective skin.
