For the zillionth time...

… what do you thin Testors enamels with if you want to do a wash?

And for the zillion and first time…

I kinda like to use mineral spirits for my washes. It thins real well, doesn’t dry extraordinarily fast, and leaves the underlying paint alone, provided it’s had long enough to adequately cure. Plus, it’s pretty cheap. You can get a quart for a few bucks.
Hope this helps.
