I put Humbrol weathering powers on a locomotive I then sprayed it with Humbrol enamel matt coat and all the powders disappeared! Should I have used acrylic matt coat spray? Any suggestions?
It's a fictitious private goods yard set in the late 40's early 50's so it's not a big deal, I'm improving a Hornby loco and just want to know how many crew to place in the cab....
