Fairly new in the hobby shops. It is a solvent based mix and they have several prototype colors including 5 for the New Haven which is part of what I model. TCP has its own thinner which is clearly said to be acetone and because I always had best results using thinner from the same maker I picked up some paint and a bottle of thinner. Directions indicate the paint can be sprayed directly without thinning starting at about 25 psi. I tried it and it wouldn't lay down smooth but somewhat grainy instead. Next I thinned it about 25%, better but not smooth so bumped to 30 psi with no change. Next I tried some application by brush and found it didn't spread very well and the brush dragged very quickly. About all I can figure is the acetone evaporates extremely fast. I am going to keep trying different ratios and even different thinners until I am satisfied. I'm not knocking the product and in fact the colors are very good. Just a little stumped in working with it after almost 40 years of spraying all sorts of hobby paints. If 30 psi won't atomize it correctly I don't see it to be a pressure problem when the paint is almost water thin.
Has anyone else tried TCP? How did it turn out?
