Hybrid is not water clean-up. - I certainly have used caulk guns many times, but I was working in a tight space. This made it easy! If your space is even tighter, you might buy the 3-ounce tube, but it is very expensive per ounce. I got the 9-ounce tube of the hybrid polymer. Which is still expensive per ounce compared to standard tubes. But the easy trigger makes it worth the money, especially when working in difficult places. There are advantages and disadvantages between silicone and polymer. For my application, polymer is much superior. But polymer is NOT water cleanup. That is not the product's fault, it is the nature of polymer sealant. You just need to know that. I did use my finger with it, and it isn't easy to get off but that is something I understood. I guess the only complaint I have with the spray can is that you can't tell how much you have left of the product. You just use it until it runs out. But the 9-ounce tube completed my project. One user complained that it was difficult to control the size of the bead even with the adjuster. I didn't have that problem, it came out great for me.
