Heres 1 of my panzers.. sorry pics arent the best but digital cam doesnt have a macro lens...well if it does I dont know how to use it..heh.
I KNOW the tracks are clean but I got weird towards the end of my building. I'd "weather" and damage and then leave clean treads..go figure.
When detailing your Uboat look for the photo etched kits that someone took a shot of, they enhance the overall appearance. The gunsite on the MG on top of the turret is photo etched.
also I was trying out different camo patterns...LOL. I started with green and airbrushed the dark armor yellow over it wich is opposite of the actual practice.
