oh and incase you care i would rec. this gun http://www.sjdiscounttools.com/ir2135ti.html over the cat gun. or even this gun http://www.sjdiscounttools.com/ir2130.html. the last one is the one i use everyday(mazda tech) for the last 4 years and it has been great. and for the money you can't beat it. i will soon be upgrading to the lighter 2135ti.
