Rubber hood to rad support seal info - read before buying

anyone ever try putting one of these seals on a fiberglass hood ??

I have one brand new in a bag (bought it at the Mopar Nationals (not sure who I bought it from). I have a fiberglass six pak hood and I thought it might be okay to attach it to the hood but I punked out at the last minute because I was afraid of damaging the hood. I instead went to the Home Depot and bought air conditioner sealing foam (about 2" thick) and Gorilla glued it to the bottom of my hood. It seals well and it gives me a nice soft edge for when I sit my hood on my vinyl top.
