## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    EXCELLENT PRODUCT!
  

*by D***S on Reviewed in the United States on June 3, 2021*

This is an excellent product. There are multiple companies buying this product, slapping their label on it, and selling it with huge markup. If you are in need for an adhesive/ sealant for high moisture situations you cannot beat this product. It is incredibly strong, flexible, durable, and waterproof.I have used this product for years now in my trade and have always been completely satisfied. YES! I recommend this product.

### ⭐ 







  
  
    not adhesive
  

*by J***. on Reviewed in the United States on September 2, 2021*

Not a good product, does not adhere as well as any caulk I have used.  Easily peels off of metals and plastics,
