If you look around (or call me), you can get specialty inserts made just for bonding into panels. For example, here's a link: http://www.gen-aircraft-hardware.com/viewImage.asp?item=NAS1832-3-3&folder=basic T-nuts and other inserts work almost as well for a few screws here and there. They take a little more fiddling to get them into the core and secure, but they cost pennies as opposed to dollars for the inserts above. Make sure the inserts are securely attached to the core and to the skin, and test how well they attached by giving the insert a good tug. Keep in mind that inserts are for non-structural applications like consoles, lights, belt and headset racks, etc. Anything that takes a load like shoulder belts, cargo tie downs, etc., need a much stronger, tested, engineered solution. My overhead light console is attached with five very small sheet-metal screws. It comes off very infrequently so I'm not too worried about wearing out the holes. I could always push a little epoxy into the hole if it stripped. FWIW, I tried to get Vans to sell my overhead console, but they were worried about the tiny holes in the inner skin of the cabin top. So keep in mind that Vans isn't going to be happy about hearing that you put holes in the cabin top. Personally, I'm not worried about what I did to mine.
