I live in Phx, AZ and the temperature outside normally exceeds 105+ in the summer. I have to paint my models outside in the garage where those temps can exceed 120 at times.
I painted last night and ended up with the paint drying almost as it landed on the model. I can fix that with some color sanding.
Would you thin the paint much more than usual so that it is “wet” when it lands on the model and takes a minute or two to dry?
If so, which I suspect is needed, how would this affect the color fastness of the paint so long as it is kept from uv light sources?
Now I’m far from an expert here, but I’d think that it would dry faster if you thinned it more. The thinner evaporates pretty quickly, and the thinner the paint is, I’d think that the smaller amount of pigment would get stranded pretty quickly. That is just my thinking though, I don’t really have any idea for sure. Have you considered using acrylics, water doesn’t evaporate as fast as thinner does. Just a suggestion.
Maddafinga points out something interesting. How about doing some experiments and let us know? I would be interested in knowing if the amount of thinner would affect the drying time. I’m in Alabama and we have more problems with humidity than the dry heat. Anyway, if you do try different thinning ratios, please let us know the results.

It is awsome.
