I've heard about this technique for german winter camo using hairspray. Can anyone tell me how to do this?
Ive seen models in all the scales done this way and the effect looks great.

Check out Mike's response to a similar question on ML. The link he post has just about everything you would want to know about the topic with input from the best modellers on the planet.
