Ok, think of this product as a new "third" kind of protection available.
For the past 100 years or so, we've had Carnauba Waxes.
For the past 30 years we've had Polymer and Synthetic Sealants.
This shares absolutely zero properties with either. This is a nano particle glass resin. It is applied to a bare surface, and once the particles cure on your paint, it will harden into a quartz layer on your clear coat, with 100% optical clarity at about 10x the thickness of a sealant or wax layer.
They make the 18-24 month claim because it is not a chemical protectant that can be diminished by a high alkaline or high acidic interefence (bird bombs, dish soaps, acid rain etc).
Where do you get this? If you use this do you still have to wax or does this replace waxing?
