I wonder why you need to use it? I mean i would never put fiberglass on a street car, you spend lots of money on an item and even more for paint, don't risk it. My best friend has a 10 sec drag LX, and I SAW him crack his hatch in literally two with stock supports. Sure they are light as a chicken bone, but they will snap just as easily as one. I would say pin it down, unless you absolutely have to use it, then just hold it in the center with your hand when you need to use it.
