Underhood insulation clips

Cautionary comment: if you have repainted, restored Mope which is garage-kept or is in a desert environment, then great. But when I picked up my 67 cuda, it had been parked outside, possibly over grass/dirt for quite a few years. It had a factory insulated hood, also. What had happened in the case of my car, was the moisture must have condensed on the underside of the hood, eventually soaking the insulation. The insulation held that dampness against the underhood structure eventually rotting it out. I now have a straight hood which looks fine on the outside, but the bracing has at least a thousand pin holes or worse.
