Review: NO MORE LEAKY FISH TANK! - Perfect thickness (dust do wish they had a 1/312” option). Had to make a custom gasket for my Reef tanks that would constantly drip from one of the bulkhead seals, tri,,e s a pice of the suite (food grade silicon 1/16” yjickness). And for the first time in 3 years the drip is gone. Was so happy that it worked so well that I changed all of the bulkhead seals to this, cuts easy, shushes just enough to seal the pressure in the saltwater. I wish I would have found this years ago!
Review: Happy customer. - Excellent product, exactly what I needed. I purchased this to prevent my tv stand from sliding around on the tv cabinet it was sitting on. (Problem solved!). I imagine this silicon mat has many uses for a myriad of issues.
