The wicked colors may be able to be sanded after dry. I painted an engine, after it had dried I didn't like the color, that paint was very tough to get off with water. Only some slight discoloration after two days soaking in water. It took Castrol cleaner to get it to budge any. Your results may vary.
The createx wicked colors are a breeze to use, easy to thin, and cover really good. Use their reducer to thin,they don't have an offensive odor.lots of colors to choose from. Flake,translucent, opaque.
You have lots of options for Paints. Lately I have been using Auto Air colors from Createx found at Hobby Lobby and some of the LHS. they shoot nicely without a lot of work before or after, cleaning is a breeze.
$40 that's way to expensive. My LHS had them for $35 but knocked off 10%. At a local swapmeet on Saturday, a vendor was selling both versions currently out for $25 each.
57 thru 60 Ford F-100 would sell very good, especially with a Larger/ wrap around, rear window version. Moebius could, and most likely will, tool up a series of Chevy trucks done the way these Ford's have been done. Hopefully it wont take as long.
