Need help building a concealment housing

I am planning on concealing my V1 radar detector in a housing mounted to the roof console. This is on a 2000 Jeep Cherokee. It will be mounted on that empty space before the rear lights. So far I plan on having smoke plexiglass on the front and rear so it can still pick up laser. I want to make this look like a stock extension of the overhead console. So far I plan on taking the console out, wrapping it in a trash bag than coverig the part I plan to mount it to in aluminum foil. Than make a base for the housing with the fiber glass over the top of the foil. I have limited experience working with fiberglass, but I have the general idea about it since I had recently repaired a boat I have. After I get the base (top) made I plan on making a clay model of the housing and lay fiberglass over that to get the housing. However, I haven't figured out a way to make the housing easily removable (if I want to move the detecror to anotehr car for instance). It would be simple to bolt it to the console, but that wouldn't make it easy to remove. I had thought of making the housing in two halves, but I don't know a simple way to join them together yet make they easily removable. Anyone have any ideas how to make it easily removable or splitable? -Chris Thanx, Chris

Hmmm... Velcro ? Magnets ?

Magnets + electronic device = not good. Velcro. I thought of that, but it really doesn't look good. I am trying to make this piece look stock. Soem form of a latch would be good, but I have no idea how I would do that. I also would prefer not to have exposed screws. -Chris

What about 3m double sided exterior tape that stuff will hold anything together. And plus if you take it down and the tape doesnt stick anymore just pull that off and put more on.
