I have used basically any brand of lacqer thinner, though I try to avoid the "earth friendly" type...I have always used lacqer thinner with my accupaint, I started doing so about 25-30 years ago......and some bottles I have are from that time, and it has never "hurt" the paint.....
The Trucolor version of MEC yellow was just too orange for my taste, when compared to the Accupaint version.....It could probably be fixed with some reefer yellow....
I made a great match for Atlas diesels using Testors enamels "yellow" and "tangerine", about 50/50....
