Thanks, everyone!
I'm at an impasse. I was originally going for an Arctic-type digital camo. I wanted something other than the standard greens/browns/tans to liven up the display.
I spent some time yesterday stripping off the old paint - it's not all gone, but it may make for an interesting effect under the new coat(s).
So, I'm of two minds on this project:
1) have another go at winter/arctic digicam
2) regular camo, but then try the hairspray method to weather a white overcoat
I'm open to suggestions.
