Any trick to this?

I have a windshield weather stripping/gasket. It's used, but in great condition. I want to reuse it on a windshield I'm going to have put in this week. The problem is, theres a lot of glue from it's previous life still pasted to the gasket. Is there a trick to getting this stuff off or just 3 hours with a screw driver?

Thanks!
Craig
