First of all, Texgal, Yardbird, and Air master, the projects look great. I like the interior details on the jet intakes and assundrious parts. Also, I agree that the F-106 would look even better with a gloss finish. I would suggest airbrushing a coat of Future mixed 50:50 with a high percentage rubbing alcohol (I use 99% myself), as this mix has worked the best for me. Aside from my nitpicking, everything looks great!
I also apologize for disappearing for a while. I have been a bit busy with the family and work lately, and when the weather was nice last week, I was out getting my first miles on the bike for 2007. Anyway, I did finish my X-15 a few days ago, and finally got around to shooting some photos this afternoon. Here is my finished project. As a side note, I did a final coat of semi-gloss to match the reference photos that I have seen of the plane on display at the Smithsonian Air and Space museum (also where I got the reference for the exhaust pattern). The external fuel tanks depicted were in a couple of different resources that I found, and I like the mix of part shiny and part flat aluminum.
As always, I am open for any feedback.
