soak them in catylized fiberglass resin and apply them to the hood in the area that you traced out for the scoop. 2 layers of the fiberglass matting. Now brush fiberglass resin to the mounting face of the hood scoop and set that onto the Fiberglass matting and let it dry overnight. Follow up with body shop procedures for filling and shaping to contour, prime and paint. Can put some weights on the scoops to hold them down while they are curing the bond. Not drilling holes in the hood for mounting is a good thing. If things would ever change you can strip them off with paint stripper without destroying your hood in the process. ☆☆☆☆☆
