General Ceramic, Nano, Graphene,… does it really matter? Estimated reading: 1 minute 94 views No, in most cases it doesn’t. There are good products under every one of these notations and there are bad products under each of these. In the end it all comes down to individual product level and not on such marketing buzz words. Also please beware, a real coating is not comparable with a spray on wipe off product, a real coating needs many different things vs. a spray on sealant that you can just apply after a wash. See for actual results and don’t look on such marketing buzzwords.
