Worked well

### ⭐⭐⭐⭐⭐ Did a great job
*by C***N on November 18, 2024*

The rubber sealant worked perfectly for sealing the frame of the window to the body of my truck. I did have to go back and fill in some places, not the fault of the sealant, just dips in the window channel. Sealed out the water and wind noise
