I recently applied the Graphene glass coating to all my windows. I followed the instructions and applied one coat. First of all, I see zero difference with water beading. Second of all, it left small hard dots on the windshield, that won’t come off. The dots look similar to a pitted windshield. I’m very disappointed with this product. Maybe I did something wrong but I watched the vid a couple of times etc. Has anyone else had this experience too?
