Re: Tru-color paint

I called Tru Color to ask the same question and was told that acetone was a relatively minor ingredient in the thinner and there are several others ingredients. They don’t recommend thinning paint with Acetone, but Acetone is fine for cleanup. Of course, they sell a pint of thinner for $43.95, so why wouldn’t they say that. Apparently, thinning with acetone alone changes the handling and drying characteristics of the paint, particularly the shiny finish.


Jon, your question raised other questions. Why do you want to thin the paint? Tru Color claims it’s ready to spray without thinning, and I’ve painted ten cars so far shooting straight paint at 20 psi with a gravity feed airbrush. I think thinning would require more coats than straight paint. I’m curious, how many modelers thin vs. not thin, and how many coats do you average for thinned vs not thinned?


One problem I’ve noticed with Tru Color is that the bottle caps aren’t always tight on the shelves, and I’ve had evaporative losses up to 3-4 ml. per bottle before I caught it. I don’t know if the caps weren’t tightened properly at the plant, or the worked loose due to temperature changes, but I suspect I’ve had some of both. I brought up the new bottles to full volume with Tru Color thinner, then really tightened the caps hard. So far, I haven’t had additional evaporative loss. Now I always check the volume, add thinner if necessary, and tighten the cap on all new bottles.

    Not having quick access to thinner is acetone* an acceptable thinner?  For the paint cup only or to be added to the jar?


* or would MEK be better?
