WHAT is this stuff called? (grommet edging around holes)

[Clint Beastwood]

If I were going to put a hole in, say, my cowl, for an intake (for example) - what is the stuff called you would put around the hole to make it more grommet-like? I am drawing a total blank - I am normally a master of google-fu but this one is evading me.

For example, the stuff on the edge of the injen heat shield thingy here

ok nevermind i went to injens website and looked at the parts manifest for that intake, its called "bulb edge trim seal". Not grommet tape

If it is a big hole you could use "Trim Lok"

Thanks - since the 2j intake doesn't really have anything holding it in place, I was going to use the bulb-edge stuff to help center the intake in the cowl hole and stop it from thumping around when reversing.
