I put a lot of time into this... the rubber grips didn't work out for me so I gutted an old broken atst I had in the garage for that center panel. The back side is filled with epoxy puty and some bondo. Primed and sanded a good dozen times and silver rub & buff applied with an old toothbrush for a nice weathered pewter look.
Nope, it was JB Waterweld - a sort of epoxy putty from the automotive department at Walmart (it's used for sealing radiators and gas tanks, loctite makes the same thing in but blue, and there's another called Quicksteel that's black - those are cheaper too).
It's real easy to work with, it comes as a stick of clay and you cut off how much you think you'll need, then with wet hands kneed it together to blend the two shades of gray untill its even, then smudge it where you need it. Hardends in a few minutes and can be sanded and filed. Then to fill the smaller gaps afterward I used some Bondo glazing putty... just glob it on and sand it down after about 20 minutes.
I've used that stuff for finishing prototype models for a 3D CAD class, and never used sculpy successfuly.
