I purchased this in-store in November 2018. Used around a quartz bathroom vanity top where "crystal clear" vs just foggy clear was important. In less than a month the caulk was turning yellow, costing much more in labor than the lost value of the caulk. The bathroom was a guest bathroom without a window or much use. So this was not due to sunlight, cleaning products, moisture etc. In fact I had kept the used tube of caulk in a cabinet and when looking in the bottom of the used tube the residue of caulk around the inside of the tube had also turned yellow. I would absolutely stay away from this product, even if it was just from a bad batch it was a total disappointment and not worth the risk of ruining a project. I see other reviews now with the same issue of the caulk turning yellow. The photos are from 4 months after installation, before starting the task of removing the caulk to replace with another product.

    DAP has another winner.
    DAP has another great product for sealing out the outside. It went on smooth and easy. This one though you can unscrew the tip and clean it out. Then put a piece of plastic wrap on and screw the tip back on to keep the caulk from drying out. I thought that it took more effort to squeeze the caulking gun's trigger than some of the other DAP products that I have used. When I took the tube out of the caulk gun, it the plunger didn't want to come out. I had to force it. There may have been a slight flaw in the tube that could not be seen or felt that made it bind slightly both pushing the caulk out of the tube and removing the plunger. That's why I'm giving it only a Good overall rating.

    One of the best caulks
    This is a great caulk (paintable hybrid silicone). Though more time consuming in application than regular latex caulk, I think it’s worth it. I tape out what I’ll be caulking to prevent messes. I wear disposable nitrile gloves to prevent messes and I use a silicone profiling kit to make a nice smooth and proefssional looking bead. Go slow and don’t try to caulk too much before you try to smooth it out. In my opinion this is the caulk you want to use when you want it done the right way that will last a very long time.

              Uncontrollable dispensing and numerous air pops
              This product, once opened with a small diagonally cut, could not be stopped. Reliving pressure didn't stop the oozing. When activity dispensing, air pops destroyed an hope of a clean line

              Thank you for posting your feedback. We're sorry to hear about your experience with DAP 3.0 Window, Door, Trim & Siding High Performance Sealant. The issue that you describe (afterflow) can result from a number of conditions (individually or in combination), including attempting to apply the product through a very narrow tip opening, application out of temperature range, gunning the product too rapidly, the use of a non-drip free caulking gun, or a small amount of air trapped under the plunger in the end of the cartridge/within the filled product. While this issue has no adverse impact on the applied products performance, it can be frustrating and messy. If you are dissatisfied with your purchase, the product may be returned to the point of purchase or returned directly to DAP for a refund of your purchase price. Instructions for this process can be found on the product package. Should you have any additional questions or require further assistance, please free to contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

              Thank you for posting your feedback. We're sorry to see your low star review regarding DAP 3.0 Window, Door, Trim & Siding High Performance Sealant. Because this is a "high solids content” formula, it will appear/feel thicker than many of DAP's other products. This characteristic translates to lower shrinkage and better single application joint/gap filling ability. It can also result in more force being necessary to apply the product. There are a number of other factors that can also impact the "gunnability" of the products as well, including shelf life and the quality/performance capability of the caulking gun being used. Should you have any additional questions or require assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

                Quick to dry in place and easy to apply when I had to fix a leak around my window! This stuff was extremely clear, just what I was looking for.

                                  I purchased several tubes from home depot this week. 10 hours after installing all over the side of the house, it is as wet as when I started. I fear it will NEVER dry, and become a huge clean up job. Why is it still on the shelves? Horrible product!
