I’ve been doing windshield repair for over 40 years. I started out as a Novus tech. I met Bill S. at a told NWRA convention at least 25-30 years ago. I tried some of his equipment ad found it to be much simpler to use with great results. All the resins and equipment are US made. They are top notch. The best thing is Bill is a guy who is talking to independent repair techs all day long. After my 40 years in the business I can still talk to Bill and learn something new. The Glassmagician give you a double bang for your buck. Great tools and extremely knowledgeable advise.
