........Vallejo Primer. After a light bead blasting followed by a hot bath in the ultrasonic cleaner, I primed a number of brass log cars and decided to paint them several different colors, one of them green. I used Tamiya medium green, a big mistake. I forgot it does not airbrush well and doesn’t dry flat, plus it goes on very thick. I decided to remove it and start over. I dunked the cars into my ultrasonic cleaner with some acetone and poof the green was gone but the grey primer remained tinted slightly green. I decided to "clean" them in my blast cabinet using medium glass beads. Surprise, surprise it stayed on the brass! Once I cleaned up the rough spots I repainted them with PolyScale and all is well. That primer really sticks........
