I purchased a silver silicone sealant for my industrial and scientific applications hoping for a tight and reliable solution for my projects. As a result of my tests, I determined that this sealant does not perform well at all.It took a long time to dry, and the final result was not as smooth or uniform as I had hoped. I was extremely disappointed in the lack of quality, and would not recommend this product to others in need of a strong sealant for their work..
