Nice Pz IV Eric, that's the kit I am doing for the D-Day GB. I hope I can come close to yours.
Eagle, one thing to remember about the German camo is that it was applied in the field. The vehicles left the factory in Dark Yellow. The other two colours were supplied to the troops as a paste. This could be thinned with anything to hand, water, petrol, oil etc. This of course would effect the final colour. It could be applied with an airbrush, but of course in the field these might not always work. So they could be applied with a brush, mop or anything else.
Eric is right in that we try to go for the perfect scheme. But often photo's show anything but. To the modeller, this just doesn't look right, I thin we are afraid it would like it had been painted by a 2 year old, even if it was 100% realistic. I think this is something we need to get over.
