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.

      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.

      The sealant was very effective and flowed from the tube very evenly. I provided the coverage that I needed. I would chose this brand again for future projects.

      Very viscous consistency straight out of the tube. At first I thought I had purchased some old caulk but after reading other reviews I believe this product is just normally very stiff. I bought this for sealing under the mounting flanges of new windows but it is so stiff that it causes the flange to buckle between nails. Pushing on the flange helps the caulk to spread but I still ended up with a "wavy" flange. It probably would work great for applications where compression isn't necessary. It cures to a flexible, rubbery seal.

        Used this to seal around some stained wood. The color is definitely not brown but more grey. As a sealant it's great, but the color is not as advertised.

          This is a great urethane caulk for exterior usage, but it needs to be said that this caulk is probably best used by "professionals" because it is not "workable" and mistakes are difficult at best to fix or remove. Urethane caulk is NOT water soluble, so it doesn't come off of things like brick, clothing, hands, etc. All that being said, if you want a great caulk to seal out the weather, forever, this is the go to product.
