## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by C***E on May 30, 2025*

I use this for driveway cracks. It works better for me than the tar stuff and cracks less with time. BUT..... it must stay dry for at least 24 hours preferably 48 hours after application! Easy to work with and blends with the asphalt driveway. Survives the winter plowing better than other products I've tried. Spring repairs are easier with this stuff.

### ⭐⭐⭐⭐⭐ As Advertised.
*by D***F on November 13, 2024*

Truly waterproof AND paintable! I'm a former contractor (retired handyman now) so I've had my share of bad experiences with caulks. 🙄

### ⭐⭐⭐⭐⭐ GREAT PRICE
*by K***T on August 23, 2024*
