Painting both Plastic & Metal

[rcman]

when i painted my box truck i primed first and then painted it. i used the same paint for the metal and the plastic with no problems. just use thin coats and let it dry with ample time between coats and you should be fine .. lots of guys here use dupla colors with great results. i havent tried them yet since i had a stock pile of tamiya paint to go thru first.
