I have a hood that has what looks like spot welds on the underside between the top piece and the cross ribs. Some of these have broken loose and let the top skin move. I scrapped it with a knife and it looks like it is some kind of hardening sealant. What is this sealant or adhesive that is used on a B body hood between the top sheet metal and the reinforcement ribs on the underside of the hood? Also, where can it be purchased? Thanks
