Bought a bottle a year ago and only used it last month for the first time. Been a Meguier's fan going through their product line whenever a new item comes along. Ultimate Wax to Fast Finish to Hybrid Ceramic Wax to Hybrid Ceramic Sealant to Hybrid Paint Coating which I bought but haven't used yet. Applied the Turtle Wax a month ago and the water still beads like it did on day one. And this is from an over one year old bottle whose formula has probably been improved since then. Still have to do paint prep for best results like clay and or polish, but might switch to TW for a top coat. I see they have a graphene product that is supposed to be even better. Anyone tried that?
