re: Anyone do a nanoceramic coating on their vehicle?

TimeSaver also does not require annual or bi-annual maintenance to maintain warranty. He does carry a product called D&S Wet/Dry Surface Synthetic Sealant. It is made by Clear Finish Products. He recommends using the product 2x a year to upkeep the original coating. It's a simple wipe on, buff off process.

Also important to note, get a detailed receipt of the transaction if you end up getting it done. File with your insurance for reimbursement in case of future wrench or loss claim of your vehicle.
