    I have used it in a storage shed with panels that I built in 2021. I also put it on the PVC frames for sealing, and around every hole and gap all around. The shed is at an altitude of 1,400 m with a lot of snow in winter! Guys, I open the door and I don’t even find a spider! After so many years, it’s the best thing I’ve tried!

    Great caution. Always wear dishwashing gloves. It stuck to my hands and it doesn't come off.
    In the end, it came off with the polyurethane solvent I bought for 4€
