Scratch removal fails for one reason more than any other: somebody skipped a step in the abrasive sequence. GT Tools Tools sells two five-step disc ladders for glass, its own SpeedGrit and 3M Trizact, and both are built the same way. Every step after the first exists to remove the scratches the step before it made. SpeedGrit says so disc by disc: Step 3 Green is "used to blend out discs 1 and 2," and Step 4 Yellow blends out 1, 2 and 3. The Trizact pages give the same instruction for the whole range, that you work down through every grade below the one you started at before any compound touches the glass. Skip a grade and those scratches stay in the glass, under the polish.

GT Tools builds three windshield repair systems and they are not three tiers of the same thing. The SuperStar SpeedLock is $772.00 and hand-operated, with supplies for over 150 repairs. The VANISH is $882.00, also hand-operated, with an integrated curing bridge and the full five-resin set. The Wizard is $3,255.00 and automated, running the injection cycle itself. The choice comes down to two things: what comes in the case, and whether the technician or the machine controls the fill. This guide covers all three systems and which is the best fit for your shop.

Setting glass is the point in a windshield job where a second technician usually appears. Someone has to hold the weight, someone has to watch the gap, and the urethane gives you one chance to land it in the right place. A setting tool changes that arithmetic by taking the weight and the positioning off the technician's arms. GT Tools builds one for this: the Lil Buddy PRO1, a driver's-side mounted device with a sliding rod and a measuring system that lowers glass into the bead without detaching the suction cups. This guide covers what the tool does, what it needs around it, and what a complete single-technician setup costs.

Powered cut-out tools handle most of a windshield removal, and every shop still keeps hand tools within reach. Manual knives go where a reciprocating blade cannot: tight corners, encapsulated glass, vehicles where the pinchweld leaves no clearance, and the jobs where a technician wants to feel the resistance rather than hear it. GT Tools stocks four kinds of manual cutter, and they are not interchangeable. Cold knives push. Long knives reach. Pull knives draw a cable through the bead. The Quarter Cutter is driven by hand or struck. This guide covers what each one does, what GT stocks in each family, and the order most shops buy them in.

Auto glass shops reorder blades more often than any other tool, and usually pick them out of habit. Choosing well takes three questions. What tool are you feeding, what is the job asking for, and how much sharpening are you willing to do. Cold knives take cold knife blades. Reciprocating cut-out tools take sheath blades. The Diablo and the Beast take SDS blades and nothing else. Oscillating tools take their own. This guide covers what GT Tools stocks in each family, how the options inside each family differ, and what a blade costs a shop beyond the price on the box.
