So, I'm trying to get back into painting and weathering. The last project I did was 2014! Back then I used Testors Model Masters and thinned it with Windex. I'm looking at possibly ordering some Vallejo paints, a set called Black and White that has a good assortment. Anybody use Badger Modelflex? I remember it sprayed beautifully but I didn't have good results thinning it down for weathering. Tru Scale has a nice assortment of railroad colors, but I believe they're all solvent based, correct? Anyway, what are you using?
