Works great (if applied on flat surfaces)

The seal is genuinely waterproof, but, application along edges or on curved surfaces tends to create ridges which leak.

Great tape and sealant

2 years ago
Worked great for the application. We used it for sealing seams on a solarium for a temporary fix. Product stuck to the glass flawlessly and created a seal to keep the water out.

Yes, I recommend this product.
