Works Perfectly - easy application, great color, heavy duty etc. I like it
Perfect - I used this stuff when remodeling my bathroom since (1) it's a great sealant and (2) can be painted (3) it's more heavy duty than regular caulk (necessary in a hot humid bathrrom). I used it to seal around my tile shower surround (between the tile and the wall. Color is great - matches the grout. Then I painted over a good bit of it. Hold paint just fine unlike a silicone sealant would. So you can fill the gaps and paint it. This stuff is also a lot more sticky than regular painters caulk and has a slight smell - I like this. Why? Because I know that means it's good stuff. Dried quickly - maybe 20 mins or so depending on the thickness. Adhered well to the tile edge/sheetrock wall - so it was easy to apply. I'll 100% get it again when I need a heavier duty sealant.

Good Stuff for where its worth it
Easy to apply with tool and fingers. Very stick so seems it will last a long time. Better than the $2.99 tubes that last for 3 years or so.

Worked well sealing a wall penetration.
I used this on a Starlink antenna cable wall penetration to exterior of the building. Easy to apply and should last forever.
