Any epoxy will do. All you're looking to do is seal the "grain" as it were.

As has been mentioned, use a sharp bit, and start small and step drill up. And go slow so you don't build up heat. A dull bit can grab, will generate more heat, and can also cause de-lamination and fluff. And if you can, you want something solid backing the spots you're going to be drilling. May be kinda tricky with the interior shape of a helmet, but a hunk of 2x4 should do the trick.

And wear at least a paper particulate mask. If you're smelling it, you're breathing it, and that is not good.
