Hi all - I have a question. I have a bunch of old Model Masters Metalizer Bottles that I bought years ago when a craft store folded. (25=A2 a bottle) I never got around to using them because all the bottled plainly state "For Airbrush Only". Recently, I got hold of a couple of Mini-Art knights and was looking at the armor and chain mail and wanting to paint them in contrasting colors. So I got out the bottles of Metalizers and chose Steel for the armor and Gunmetal for the chainmail. Before I realized it, I was brushing the paint on and found that it quickly dried and left NO brush streaks. So why was it "For Airbrushing Only"? The stuff works perfectly.
Oh one other point, I put a recycled rattleball from an old spent can of spray paint into the bottle too, to keep the paint mixed. That works nicely.
