What is this metal on a B-58 engine cover?

Just a SWAG, but I would guess titanium. 

You are probably correct. Thanks!

Does anyone know of a good titanium colord paint. I have tried testors' Metalizer Titanium paint in the past but it is too dark.

Yes, probably titanium over the burner section. I'd give Model Master Titanium enamel a try or MM Burnt Metal or Jet Exhaust. Any one might be match.

According to page 477 in "Bonded Bomber" by Smith and Rogers in the SAE Transactions periodical from 1962:

"These areas are made of brazed stainless steel sandwich because of the heat of the engines"

The Hustler also has some fiberglass, including the radome and I think the fairings on the top of the wing over the landing gear bays.

I would have loved to see one fly.

Thanks for the great information. 

Here is a photo of the plane under construction. Immedietly to the right of the tail wing is the fuel tank that hangs under the airplane. An atomic bomb was placed within the fuel tank.

This is a closeup of the construction. The shape of the wing spars is pretty interesting.

You know, I was just thinking that it looked like stainless, but figured titanium made more sense. Interesting that it was brazed, I wonder what alloy they used, and what the melting temperature was...

Quite the aircraft.

The bomb was in the pod, but separate from the fuel. The fuel in the pod was for the run in, the whole thing of course was dropped in theory on target.

Despite some rumors to the contrary, no one ever rode in the thing.

Yes, the wing is interesting. No main spar with transverse ribs, just a lot of smaller spars.

If memory srves, the inlet temperature of a J79 was about 900 c.

He means the turbine inlet temperature!

Thanks for finding that web site. I looked but I cannot fing the blog that you are refering to. Can you include a link.

Try this link for the blog on the site.  https://www.oldmodelkits.com/blog/ 

If that fails look on the very top of the front page of the OldModelKits Home Page and there will be a tiny link called "Plastic Model Kit Articles and Howto's"

There are some great "how to" articles and a lot of vintage kit history and kit reviews. 

Good Luck! 

Thank You " G " : 

I was going to say about the same thing .Dassault-Brugier also used the sandwich panels on their own engine cases .When they went to Garret Air-Research engines it was definitely different . The wing spars were made of bonded material that was a Honeycomb material and very strong and light .Vertical or horizontal it all worked . T.B.   I did get to see them fly for about four months at L.R.A.F.B. when it was still a S.A.C.Base .WOW ! Noisy and Beautiful at the same time .

JohnnyK, Apologies for not getting the info to you sooner.  I'm new on the forum and I think I have to do a few more posts that are moderated before they turn me loose.  Regards.

Tanker-Builder, I never got to see a Hustler fly, but they had one on display at Kelly AFB, TX many years ago.  It looked as fast sitting in the hangar as it probably was in the air. 

I'm not sure if I should thank you all or not in this thread.  I'm going to have to buy and build one of these beauties now.  Cheers! 

The B-52 was Dr Strangelove, the B-58 was Fail-Safe.
