What are you guys using to cut the holes out in your cowl? Some of the pictures I've seen on here show really clean cut holes. I'd like mine to look nice too. I've got a dremel tool and a drill. I'm sure I'll need to use the dremel to cut the air intake in the front, but was wondering if a regular drill would work on the round access holes. Sometimes certain bits can tear fiberglass to shreds. I don't want that to happen with mine.
