HydroSilex Recharge is a universal product that protects virtually any type of surface. The installation is extremely easy and once cured, it creates a transparent top layer that adds gloss and protects the substrate from the elements. HydroSilex Recharge can be used as a stand alone product or as a maintenance coating to revitalize other ceramic coating brands. You do not need to be certified or trained to apply HydroSilex, its that simple to use! Our 32oz is great for those large projects and shop use.
