Hood pulling away from supports

I've had windshield urethane "suck back" and distort metal. I'd use Fusor 800. It's a urethane product also.
Make sure the hood is in its natural resting position and not upside down on a bench which may fossilize unwanted contours . Clean the contact surfaces well and use your finger to force it deep into the braces leaving a finished appearance. Follow the recommended painting procedure.
