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.

Auto glass inventory has to live somewhere between delivery and installation, and how you store it decides how much of it survives. A glass rack holds windshields, back glass, and side glass upright in padded slots so pieces stay separated, off bare metal, and clear of shop traffic. The question for most shops is not whether to rack glass, but which format fits how the glass actually moves: mounted in a vehicle for mobile work, fixed in the shop for staging, or both.

Large glass is fragile, heavy, and prone to breaking when it is tilted flat, allowed to move, or handled by too few people. The central safety principle is simple: keep the sheet upright or near upright, protect every surface and edge from contact and vibration, secure it against sliding and tipping, and handle it with a properly sized team or suitable lifting equipment. Everything below follows from that.

Hard water spots build up when mineral-rich water dries on glass, and the fix depends on how far that buildup has gone. This guide works in staged steps, from a gentle test toward a dedicated glass-safe remover, so you match the treatment to the actual condition of the surface. The same logic applies to a shower door, a window, or a windshield, with adjustments for each.

Professional glass work asks more of a spray bottle than any household cleaner does. Technicians spray solvents, water-based solutions, and polishing liquids all day, often in and around vehicles. A bottle that leaks, clogs, or degrades against a chemical wastes time and risks the glass.

This guide breaks down what each amount includes, what you buy separately, and which class fits occasional work versus high-volume shop use. All prices are GT Tools list prices checked August 19, 2026; confirm current pricing on each product page before ordering.

Choosing between manual and powered molding cutting tools comes down to the job in front of you, not the category label. In auto glass work, three tool types show up most often: manual molding cutters that shape trim and molding material, manual cut-out tools that separate the windshield from the pinch-weld, and powered oscillating cutters that drive through urethane with a motor.

Suction cups grip, lift, position, and set non-porous glass safely, provided you match the cup to the job. The right choice depends on glass shape, cup profile, the load you need to hold, how many technicians control the glass, and whether manual pumping or a battery-powered vacuum fits your workflow. This guide covers handling and setting glass after the cut-out work is done, so it treats suction cups as handling tools rather than cut-out equipment.

A fresh crack in your windshield rarely stays the same size for long. Temporary protection can limit contamination and lower the chance of further spreading, but it is not a permanent repair. If you want to know how to stop a windshield crack from spreading long enough to reach a technician, the practical answer is to control debris, temperature, and vibration while you arrange service. A crack that reaches an edge, blocks your view, or branches in several directions needs professional assessment, not a wait-and-see approach.

Mobile auto-glass work asks one tool package to handle everything at the vehicle: inspecting damage, injecting resin, curing under UV light, finishing the surface, and restocking before the next stop. A windshield crack repair system for mobile technicians has to travel well, set up fast, and give the technician manual control over each step. The right choice depends on your service mix, your power routine, and the consumables you keep on hand.
