rattle cans in 30c approximately

[tigercat]

During hot weather some of my paint is coming out cracked .

I'm using humbrol spray paints . It's not every time or with every colour .
.is it down to temperature ?

I usually have more problems when it is cold. Can also be to old paint and the surface you are applying it too.  Cheap spray paint primer can help.  If they are really old cans, toss them.

I've got that in most weather conditions and I've put it down to being to heavy handed with the spray. High temperatures might be making the paint come out "heavier" ?
