Just found this post How do these escape me???
Polly Scale was, IMHO, the best acrylic available at the time (I haven’t tried them all I’m sure). If you could see me around my stock of Polly Scale, you would think you were watching Gollum with the Ring.
I really like LifeColor but they do not yet have US rail colors. (Do you like to mix your own?) I tried some Vallejo railroad colors and liked them but they are a simple weathering set.
If Badger still makes their ModelFlex, I’ve used it. Didn’t like as much as Polly Scale but at least they had railroad colors.
I won’t say I hate Testors for sending Polly Scale and Floquil to the scrap for their crap, but I won’t buy Model Master since they did so, not that I bought much after Polly Scale came out.
Now this is one of my tricks. I have begun using craft paints. Look up Jason Jensen Trains on YouTube, he uses them a great deal. I started fiddling with them almost 20 years ago and airbrushed Apple Barrel brass onto the radiator of a WWI German plane. Worked good.
