When y'all are getting down and dirty with the Dremel, how do you keep the tiny metal scraps from scratching your case?

When I watch my buddies over at Orange County Choppers do their metalworking they're constantly flushing water onto the piece to keep it from getting scratched to crap. This is a little unrealistic for me, but I was wondering if y'all have any tips for this young soul who's about to venture into his first Dremel job.

God help us all.
