Hi Folks
I seem to be having a problem with Matt Tamiya Paints, I prime my parts with Tamiya Primer and then airbrush Tamiya matt paint using Tamiya thinners.
Even after a couple of days, the paint seems to be soft the more I handle the model the more I loose my nice and even matt finish. The handling seems to leave a sheen on the edges, this can be emphasised even more if I was to rub the object with my finger.
Before I start each model session, I would wash my hands to get rid of any greasey fingers, so what elso could cause the problem.
