Glass Pro Systems of Monroe, Wis., has recently been granted a second patent on "The Cinch," its auto glass repair device.

Patent number 6,663,371 was recently awarded to Michael Curl, owner of Glass Pro Systems, following an earlier patent issued this fall. The Cinch uses dual vacuum chambers to pull air and moisture from damaged windshields before resin contacts the glass.

Curl offers hands-on training for the system at company headquarters.
