Just send me a pad and I will coat it for you to try. Slow Release Coatings can be based on any microcrystalline or compositional powder. They can be used with any commercial system out there. My Hard Water, Glass Renu;… anything! No more messy slurries and compounds. Save time, and money. Remove stains, convert glass to hydrophylic, activate glass surfaces to receive hydrophobic sealants, and use for low e coated glass. Below is a picture of a two inch pad. The base is hard felt with a crack and peal adhesive back. The top has been coated with a slow release formula. Not my imagination guys. I have done this. Will be working on videos soon. There will be an entire line of these pads. Email me with any questions or just ask me right here.
