Just tried it and it seems really solid. The hood skin is definitely bonded to the hood frame - no problem there. I'm thinking that perhaps the left side of the hood needs to be more firmly closed down onto the vertical screw adjuster. It looks perfect sitting in the driveway, but starts to fly at 45 mph, as I mentioned. Perhaps I could adjust the hood latch further down vertically, then move the left vertical adjuster higher. This may more firmly trap the hood against the vertical rubber bumper.
