Dries completely clear and good quality
Works great and dries pretty quickly. Used it indoors and started to skim in about 30 mins. Only bad thing is the strong sour smell when it’s wet and it is a pain to wash off fingers. This is normal for silicone caulk though and a sign it’s 100% silicone which is a sign of quality for waterproofing. Once fully dried to the touch after about 18 hours there was only the faintest sour smell that went away after another 12 hours and it’s fully clear which is great. Good quality for the price.

Great caulking, goes on smooth
Great caulking, goes on smooth so application was pretty easy. Dries quickly as promised. The only thing is the very strong smell. I havent had it on the tub for very long so I cannot speak to it's versatility or how it stands up.

EXCELLENT PRODUCT. Application tip below.
I got this specifically to seal seams in my all-tile bathroom. The bathroom was renovated almost 7 years ago, so there were 7 years of showers, steam, hot weather, cold weather, etc. The tile holds up; the grout mostly holds up, but seams between planes tend to separate. The separations can be so small that you can't see them, but when someone spills a bowl of water near the corner of the room, it will, for example, show up as a leak on the ceiling of the room below. Hypothetically. <g> I learned a trick for getting a clean caulk line and ensuring the caulk makes full contact with the seams. I use a formica sample, but a credit card will do. It just needs slightly rounded corners. The other thing you need is a spray bottle with denatured alcohol in it. Apply a thin bead of caulk, then immediately spritz with the alcohol. The alcohol keeps the caulk from "setting up" too fast. Typically, people use their finger to smooth the caulk line. Don't do that! Use the credit card or formica sample to smooth the caulk line, wiping off excess caulk as you go along. The alcohol gives you extra time before it evaporates and the caulk gets messy. I did most of the places where the tile walls meet the tile floor, and in the shower where the walls meet at the corner. It's probably better to do it *before* there's a leak!

GREAT PURCHASE FOR BATHROOM CAULKING!
This caulk worked great on my tub! The consistency was just right not too runny and not too thick which made it really easy to apply. It smoothed out nicely and gave a clean, professional-looking finish. I also like that it’s mold and mildew resistant, which is perfect for bathroom use. Overall, very easy to work with and the results came out looking smooth and neat. Definitely a great product!

Typical of the quality we have become used to with the Gorilla brand
We used this to try to fix the lint trap on my dryer. The metal screen was rusting and tearing along the edge. No way to replace the screen or purchase a new lint trap. One bad of silicon asking the torn edge and seems to work perfectly fine.
