You know, John... I'm finding myself spending more time examining your photos than I spent lookin' over the real truck that one time I had the chance! I have to compliment your photo skills, too. That makes a big difference at this scale.
I especially like the way you handle paint finishes. Flats, semi-gloss, metallics. That goes a long way toward a convincing replica.
Question about decals: Do you have a preferred decal manufacturer? I've only made custom decals twice, and got different brands each time. One was noticeably more opaque than the other over darker body colors. I remember one being Testors, but I didn't notice the opacity issue until I have disposed of all the left overs; so I couldn't tell which was which.
Also, being new around here, I've got to ask if you're scratch building most everything we're seeing in these photos? I mean those coolers and radiator in the front of the chassis are unreal! I'm curious if you're able to pull parts from other kits, or if you're building most of your components as you go.
Great work!
