Tony, it's not plasma spraying - I think that's a little more high tech than this. This is just plain old (VERY old) metal spraying. All you need to do it yourself is a spraygun with a big tip and an arc to melt some alum wire. Not quite as simple as that, but that's all the gun does. You can spray a foam cup with it, and as long as you don't try and coat it in one long continous coat, it won't even melt the foam.

Curtis, what was the diference in appearance between the metalmorphed P38 and Flitemetalled planes? The P38 looked good in pics, but then again so do most planes, esp when they have some shiny silver on them. I get the feeling the surface may not have been "fair" enough to look scale.
