Hey there guys.
I'm having a huge problem at the moment with spray paint cracking whenever I spray one of my models.
At the moment the model in question is an Eldar Wave Serpent. Around all the edges and crevices the spray paint begins to crack after a couple of minutes. I've prepared the model by washing it etc in advance, and no matter what brand of spray paint I use, this always seems to occur.
Have you guys got any tips for me to help me avoid this as right now, it is seriously driving me to the brink of insanity!
Thanks in advance, Zen.
I'm not an expert on spraying (I usually brush on everything, including primer), but my guess is it's the paint itself, not the manner in which you put it on. Are you sure it's mixed properly? You say you've tried different cans. Have you tried different manufacturers? Is it paint made for modeling or something else? How old is it? Is it brand-new?
It needs to be warm, and it has to be very well shaken.
(especially if its old or has been sitting undisturbed for a while.)
Yeah my suggestion is to follow the guidelines for use on the can. Humidity, temperature, spraying distance... if any or all of these are outside of their parameters you can get odd results including cracking. Paint does shrink a bit as it dries and you might have an issue of spraying too close and too much and as it is drying it may be cracking.

From my experience, cracking is most likely to have to do with the ambient temperature. I used to get some cracking when I would spray in my basement when it was cold, even though it was still indoors, it was only ~50' down there.
