Hi guys,
Thanks for the kind words and am happy you all like it. It was a very long and involved project that took way longer than expected. Modern subjects can't (or I might say "shouldn't") be treated in the same manner as WWII armor, something looks off when that happens. So I had to try a different approach with this one. Fortunately, this dozer had lots of extreme weathering opportunities to explore such things.
Yes, all the chips for each color were achieved with HS layers, about 5 layers in total depending on the area. Each color was sprayed, then covered in HS, then chipped and sealed, and the process repeated for the next layer of paint. In fact, it was very straight forward, no real surprises and all the paints used were Tamiya because of the fine chipping qualities discussed in the HS thread here.
I'll be able to post more detail shots after it is published. I believe the Sept. issue of TMMI will have it.
Here is the main ref. photo used...

Best,
Mike
