It is late here in the UK (2am) and I have just finished weathering the Mirage Pz IVD. I intend to put the finished model in a mini-diorama at a later date, halted on a road somewhere past Sedan and with either refugees (first choice) or Heer marching past, but that is for later.
I have seen lots of photos of vehicles in the Fall Gelb campaign and they seem to have a moderate amount of accumilated mud and a lot of dust, I suppose it was quite warm and dry in May 1940. I used some Games Workshop Earth and mixed it with MIG European Dust to produce a slurry, which was carefully caked on the lower hull, along with the lower front/rear. I tried not to overdo this as I haven't read of excessively muddy conditions in this campaign. As the slurry was drying I dusted a small amount of pigment to represent dried mud, after this I liberally dusted the area with pigment to represent the hard travelling some of the Panzer units did. The tracks were given a light coat of this slurry and dusted with pigment as well. I tried to be as restrained as I could for the upper surfaces, concentrating on the edges of the hull and other areas to create a build up of 'road dust' in these areas. When I was satisfied with the hull I moved on to the exhaust, I again made a slurry of Tamyia Hull Red and MIG Rust. This was carefully applied to the main exhaust and then the rust effect built up using Vallejo reds, yellows and red-browns to get the effect I wanted. The finished result was then dusted with the European Earth to blend it in and harmonise it with the rest of the tank.
Quite an evenings work and I have a result I like, here are the pictures, hope you like them:









The pictures aren't the best I've ever taken, I will do some better ones to post in the gallery, anyway now it is onwards and upwards with the Stug IV, should be able to finish it in 6 weeks.
All the best,
Paul
