    I know my way around caulk. Ive used many different caulks in my life but of all the caulks Ive used this is my favorite caulk. I just wished it vibrated.

    Went down easily using a caulk gun. I would have loved some instruction on how to get it off my finger after I made the mistake of smoothing it without a glove. Just in case you need to get it off, soap, mouthwash, alcohol and nail polish remover weren’t successful. I think I finally got it off by pouring a little bourbon on it. Desperate measures...

    Its a nice product that have shown what it can do once its dried longer than 30 minutes. Saturday I used this sealant to chaulk my windows and doors. It was around 42°F when I had done it. It had started to rain around 4 hours after. The next day was around 47°F. I checked the sealant to see if any cracks were present. Ran my finger on the sealant to find out it hadnt completely set. Watery sealant on my finger. Sorry, dont trust the Thirty Minute Rule. So today I applied it on the back side of the house with 61° with sun/no clouds. Will check tomorrow if all is well.

    Was just as advertised. Was easy to apply and looked good. I mainly chose this one because it had the shortest curing time. Plus Gorilla brand had a pretty good reputation. Pleased with the outcome.

    This product doesnt come with any kind of a cap, so there is no way to prevent the caulk from drying out. I suppose you can say that the caulk itself forms a cap, and the next time you use it just pick off the dried part? I have not used it for a second time yet so Im not sure how easy it will be to remove the dried part.

    Great product! I wish there were better instructions though. I broke two caulk guns before I realized there was a seal under the screw on tip that needed to be punctured.
