I've read that stretching it as you're applying dulls it a little, and tapping it with your finger dulls it more. I think it was BA that posted a pic of a particular powdered makeup product that you could tap into it to reduce shine. Seems like that would be very effective - a little flesh/scalp colored powder at the hairline right in the glue....maybe I'll go to a bartell's a couple counties away wearing dark sunglasses and a hat and trenchcoat and surf the maybelline isle...
