Honestly it seems like quite a bit of hype.
I would seriously question if CSC lasts one year, especially through our Canadian winters. It honestly looks more like a sealant than a proper durable ceramic coating.
As far as I know, the real king of sealants still is Jescar Power Lock Plus, but it isn't a spray sealant, you have to apply it by hand.

Most people I know recommend you put a top layer of Collinite 845 wax on top as a sacrificial layer that adds insane gloss.

I personally have never used this combination, but this is literally recommended everywhere.

What I personally like to use as a spray sealant is GTechniq C2v3. It also is a Si02 spray sealant that has really insane gloss and durability. I put it on everything, paint, wheels, front windscreen. It holds up really well in the summer and pretty decently in the winter. But most of all it is super fast to apply and looks incredible.

Shortly I'm going to try CarPro Reload and compare the two.

Also you can but all this from Bocar in Saint-Laurent if you want to support a local business and not have to wait, but their prices aren't as good and you have to pay QST where Carzilla is QST free and they have slightly better prices.
