Another great choice Bill, seem to remember you done wonders the last time you got to work with weathering over zimmerit, was it your stug IV ? I just spent the last hour stash surfing I was sure there was one of these in there somewhere.
I bought it as part of a job lot from some guy who was selling off his stash, the real surprise was that I was interested in a Brumbar after seeing Tony "PVT. MUTT" Lees great work on the brumbar and this guy offered me the M10 Panther, Wirblewind, PzII F with interior all for about €150, couldn't resist. I hate the Wirblewind since I built a 1/72 one as a kid. When I seen your post earlier I had to find mine, and low and behold I must say it is one beautiful kit, oozing quality.
Does your Zimm kit include zimm for the hull roof, I think the wirblewind is the only time I have seen zimm even on the driver and radio operators hatches.
Anyhoo good luck with your build I'm sure it will be a top notch build.
Regards,
Terry.
