There is a painting tip for the Acrylic paint fans in the meat of Stik's last post.
Whenever you are going around from hobby shop to hobby shop, if you happen upon some of the Polly Scale Railroad paints, pick up the blacks, the metallics, the reds, the blues, some of the greens, and the grays. (Sante Fe silver is one of the best acrylics to use for the "silver lacquer color" painted on some aircraft)
You will most likely see them for some sort of sale price (anything less than $6 for the 1 oz bottle is a sale),,,,,,,,but, you can still bump into them now and then. Avoid any bottles you see labeled "Polly S", no matter how many people confuse them, they are very much NOT the same formula as Polly Scale. The difference is as obvious as the new style Model Master Acrylic paints and the old formula with the Gray caps on them.
Even if all you find is some of the black colors, you will have the best Acrylic for brushing and airbrushing until you use it up. That is why people miss that paint so much, it just flat out works the way paint is supposed to work.
