      Hi,

      I'm currently building the Pan Am Boeing 747SP of Authentic Airliners.

      My problem is that I'm not quite sure about the right tone of the grey wing-body fairing around the wing roots. Is it perhaps of the same color as the coroguard of the wings and stabs, or is it
      of a different grey? If so, which would be the best paint in the market for that area?

      And then another question, in your opinion which would be the correct paint to use for the coroguard areas?

      BR

      For what it's worth, here are the painting instructions for the Platz 747SP kit, by Jennings Heilig. This is for the Korean Air issue, but IIRC the Pan Am version (which I have at home) is the same:

      As for Coroguard, you'll get as many different answers for that as there are modelers. I usually add a few drops of dark gray to aluminum paint until I get the effect I'm after. Coroguard is a notoriously tricky color to capture and changes appearance depending on lighting and other conditions. It's one of the most subjective things I've ever encountered.

      Hi Seutula,

      I have recently completed this same model see here

      https://www.britmodeller.com/forums/index.php?/topic/235080945-1144-authentic-airliners-panam-747sp/

      I painted the wing body fairing and wing areas Boeing Grey and used an enamel paint only available here in UK. Mr Color 315 is a very close match to Boeing Grey though and is available on eBay or maybe your local model shop.
      For the Coroguard I add a little Gun Metal to Polished Aluminium.

      Hope this helps.

      Cheers,
      Ian

      Greetings,

      I use Tamiya 87064 Grey Fine Surface Primer L Spray for coroguard. For metal finishes I use Tamiya Bare Metal Silver and for Boeing Gray, I use Boeing Gray I get made by these guys:

      https://www.myperfectcolor.com/paint/434511-flint-fds-boeing-light-grey

      If you buy one can, it is very expensive. Buy more more than a couple then the price comes down. It is spot ion for Boeing gray though.

      Good luck,

      Mark

      Having observed, photographed, and generally pondered over literally hundreds, if not thousands of real aircraft, photos of real aircraft, samples of paint, etc, I've never once seen any real *noticeable* metallic effect to Corroguard paint. I know the real thing is aluminum powder mixed into a clear carrier, but it's so finely ground that it really just looks like grey to my eye. When I first posited the idea of doing Corroguard decals back in the mid-1990s (the response to which was WILD enthusiasm and amazement), my original intention was to do them in plain grey. But everybody convinced me to do them in a metallic grey instead. I've never liked them that way. If you sit on a real airplane with a Corroguard inspar area, five feet away, you simply cannot, even in bright sunshine, see any metallic sheen to it at all. If you scaled down the size of the aluminum flakes in Corroguard paint, they would literally be atoms in diameter, and no decal ink or paint has flakes that small.

      The WBF, I'm pretty sure, is Boeing 707 gray.

      For coroguard, I usually use medium gray with a few drops of aluminum mixed in, gives it just the slightest metallic hint, but mostly gray. As far as how it looks "in real life," it can be anything. Check out this picture series for reference: https://airlinercafe.com/page.php?id=440

      I'm interested, and a little relieved to hear this. It means I can just use grey paint without . What I'm curious about though is
      1. why, if it is true, coroguard is so variable dependent on light
      2. What is the closest plain grey match

      1. I can’t give you the physics, but it has to do with the physical and chemical characteristics of the “paint”

      2. As with most things, the answer is, “it depends”. I’ve looked at the exact same aircraft from inside the terminal and it looked one way. Then I boarded that very aircraft and viewed it from inside the cabin under overcast skies, and it looked like a completely different color completely. Then we took off, and at altitude in bright sunshine it looked like a **completely** different color yet again.

      Coroguard is "so cool". The combination of bare metal, Coroguard, and Boeing gray is fascinating. Under different light all three colors can look very similar. Coroguard is probably the most interesting of the three. I found reference to Coroguard being used on military jets in the 1950's. Simple answer for modelers is that a simple gray won't really be a good match. I've added some dark metallic paint to gray. As Jennings mentioned Coroguard appearance changes so much depending on lighting. So there really isn't one paint color to get a perfect Coroguard match.

      Both McDonnell and Grumman continued using it well past the 1950s. As delivered, F-14As had Corroguard (note that the brand name product is spelled like that) leading edges on the wings, stabs, and vertical stabilizers. All F-4B/C/RF-4B/C, and early F-4Ds were delivered with Corroguard leading edges as well.
