Thx JP - sprayed em with a base of flat white enamel, then flo green (rustoleum), was the only green I could find to match the vanes.

Crested with Testors enamel, then dipped em when done in a water based polycrylic.

Don't know how much weight I added to the shaft, but saw a video on spraying and the guy showed that one coat added about 1 grain of weight, so with the 2 coats and dip of poly I'm guessing I added 5-6 grains of weight. Need to get a digital scale - heck I need to get a lot of stuff.
