While painting my Model T, I decided to try the airbrush I bought some time ago but never had a compressor to use it with until I got one on a long-term load.
I cut my paint (Model Master Classic Black) with lacquer thinner like I have before. I found with the lacquer thinner previously, the paint dried very quickly and I got a nice, level, glossy finish out of it.
I'm now finding that the paint doesn't dry quickly, and that it's still drying like enamel- S-L-O-W, and Testors black in particular- E-X-T-R-A--S-L-O-W. The gloss is also not present, especially after sanding between coats. I'm already planning on a polishing kit and a coat of Glosscote at the minimum to bring it up. Barring that, I may just strip and re-start, but I'd really rather not.
I suspect it's the lacquer thinner reformulated to not work properly anymore, which means I might need to grab some next time I go to New Hampshire where you can still get the good stuff, or I'll have to ante up for the PPG automotive stuff, which does most certainly still work based on recent experience of others.
The product in question is the Ace lacquer thinner.
I'm just curious if anyone else has experienced this and if a solution was found.
