Tube split and ruined caulk gun.
Had a tube split and thought it was because it was old caulk. Bought two new tubes and started to apply in dry, 80 degree weather. First tube split the length and filled gun with sealant. Spent more time cleaning gun than job should have taken and still have to replace the caulk gun, rod bent and barely advances even at high speed setting. Where do I send the bill for reimbursement? Have applied hundreds of feet of different caulks without any problems until this caulk.

We're so sorry you had this experience with our product. What you described isn't characteristic of OSI QUAD when the nozzle opening is cut large enough and the inner foil seal has been properly punctured. If you ever need assistance with our products, feel free to reach out to our team at 1-800-624-7767. OSI
    Good product but messy.
    After I had a 2nd tube burst/leak I decided to leave a review.

      QuadMax is Great
      [This review was collected as part of a promotion.] I work with an Aluminum contractor doing metal roofs and additions. QuadMax is one of our preferred brands because of its durability, longevity and ease of use. The detachable snout makes it easy to store in a truck or tool box. The slice off the top opening means you don’t have to use the puncture rod on your caulk gun. I love that because it makes the job so much cleaner. QuadMax has claimed to have improved their clear to last for years. Time will tell, but either way this is a great product and worth every penny.

        Great Product & Great Seal!
        [This review was collected as part of a promotion.] I recently used this product to seal several areas in my basement and around exterior windows. The product worked great and provided a smooth and seamless seal. For my application, I used the "clear" color which provided the look I was going for. The adhesive seems extremely strong and really holds everything in place while waterproofing at the same time. Odor was minimal. If using on cold days, I would suggest warming to room temperature in order to get a smooth and steady flow. Very pleased and will be getting more to finish up the never-ending to do list.

          crystal clear with excellent grip!
          [This review was collected as part of a promotion.] Quad Max Clear is an excellent solution to address any number of areas that need a watertight seal. The number of options for a clear and durable solution are somewhat limited and Quad Max does not disappoint in any regard.

            Good brand
            [This review was collected as part of a promotion.] I used this for a room addition and I’m completely happy with it’s performance. It was easy to use, inserted into the gun just fine. Dispensed great and didn’t drip like crazy. Was easy to smooth on and dried quickly. I was able to paint the same day. I will be switching to this brand for all my home improvement needs.

              I've had this in place for about 2 weeks. This was recommended by a high end window installer with the highest recommendations. I'd rather pay a little more and get better lifetime coverage, than to keep reapplying every few years. This is really tough stuff and awesome to apply. Does not shrink or peel, which is very important to say the least. Another good feature is that it has a self puncturing seal, so you don't have to insert a tool to puncture the seal initially. I'd recommend wearing vinyl gloves, once this dries on your hands it's very tough to get off.

              Excellent for Energy Efficiency Projects
              [This review was collected as part of a promotion.] This product is easy to use, strongly bonds to all types of siding and windows products! After using OSI Quad Max, I will not use any other caulking products. I used this product on a siding installation during cold, wet weather and had such great results. I was very pleased with the smooth finish.

                Great wet application
                [This review was collected as part of a promotion.] I needed a product that I could apply in the rain. Quad Max worked great. We sealed a leak along a masonary wall where it met a metal window frame in a light rain. The window was leaking and it stopped. Thanks OSI
