Review on 🚘 3M 08609 Windo-Weld Super Fast Urethane Cartridge 10 oz: Strong Adhesive for Automotive Glass by Rich Ferguson

Super fast is putting it mildly. Urethane has been used on the windshield in all vehicles since 1991 to hold it securely in place when the passenger side side airbags deployed away from the windshield. If you don't feel like doing it yourself, stop and call a professional installer. When the installer tells you 30 minutes, say goodbye and move on to the next. This urethane has a maximum waiting time of three hours before it can be removed, this is due to the passenger side airbag should you get into an accident. This urethane is fully cured in 72 hours. Avoid car washes and heavy rain for the first 24 hours. If it must be outside in the rain, yes, no one can control the weather, and not everyone has a garage, use 3M quick release tape everywhere to stick the top and sides of the windshield for 24 hours to prevent intrusion so much rain as possible. Urethane will not dry properly if excessively wet. After the rain and when it's safe. Use a hair dryer in high heat in the car around the dashboard, side pillars and ceiling and on the glass to speed up the evaporation of water. There are no external effects when using a hair dryer. Never use a heat gun, you risk breaking the glass and melting the plastic trim. Once you have primed 3M 08681 on both the glass surface and the weld and allowed 5 to 15 minutes for the primer to cure, you can add the urethane. It's best to cut off the tip to get a 5/16 inch wide bead and slice it into a pyramid shape, making them at least 9/16 inches deep and 5/8 inches high. The pyramid has long been the industry standard as it allows more urethane to be fed in a straight line, reducing the likelihood of it extruding when installing glass. A power sanding gun is preferred for applying urethane but is not required. If you're using a hand-pump grinder gun, you'll need a good grip as this material doesn't want to exit the tube. You'll switch hands every two feet you press. Yes, it's so hard to get out. You must have disposable gloves, a shirt and pants that you don't need. Anything that gets on this urethane will never come off. Period. That includes the meat. Once you've installed the windshield or glass you're installing, you have about 15 seconds to make minor massage adjustments that the glass needs to align perfectly. This was the first time I used this urethane. Like I said, ultra fast is an understatement, it sticks almost instantly. I cannot recommend this product for the first time user. I would recommend the slower setting urethane that 3M offers for a first time installation or a do it yourself installation.
