I think I did the camo a bit dark on the Panzer IV's. As I recall I used a ration of 1:6 of Paint and water for those but went with a a much thinner 1:10 for the panthers. I then painted the camo stripes twice until I built up the desired density of pigment. Thin enough to look (from a distance) as if they had been airburshed. I still need to experiment as I'm having problems maintaining consistency in the finished results from one session to another.
