OldDan and Hollywood, that's not exactly correct. This past summer I had an opportunity to do a very close-up walk around and examination of the USAF's newest stealth fighter, the F-22 Raptor.
The skin of the aircraft, unlike other aircraft and stealth aircraft is made from a different material that actually absorbs the radar power rather than simply reflect it. The plane is totally invisible to radar and, if they want it to be seen by radar, they have to attach a piece of equipment to the bottom of the plane that will reflect the radar energy.
Those are my grandsons in the photo above. When we got the tour of the plane the pilot asked me not to touch the skin of the plane and also not to take any close up photos of the skin. Once I got up next to it (within arm's length) I could see the structure of the skin and could see why he didn't want me to touch it or photograph it.
