Guess I could update this, with my results...my help someone!
The Uschi set has different options for color and grain/texture...ranging from a very light brown/tan, to a more orange-ish tan.
I did some test shots, with various under colors...
I went with a mix of tan, with a bit of a yellow tint. Using the various sheets, you can see the difference in color and grain...
The unfinished area will end up in camo colors.
Overall, these decals were fairly easy to work with. For each panel, I would cut just two sides of the decal to fit the angle, leave the rest just a touch on the big side. Once laid in place and dabbed, I used a new #11 blade to cut the decal down the panel line and remove the excess. It's slow going and tedious, but the results are well worth the effort and curses!
