Up for sale is a nice Glass One windshield repair injector. Simple, easy to use, very powerful. This uses orings for seals instead of rubber tips, making it more powerful than most windshield repair injectors until you get into the 0-600 range. Simple secret that no one else seems to be using. Enjoy the power, this unit is very low cost allowing you to get your feet wet for a low cost, or add multiple injectors so you can do fleet work. Believe me, when you get 4 cars approved on a used car lot, you won't want to do them one at a time! Pick up a couple for your toolbox.
