I've used Cancoat a couple of times and liked it a lot. My bottle is about 3 years old now, so who knows if it's actually useable anymore. It's still liquid but seems a bit thicker than when new. Most likely it'll be very grabby to wipe off now.
Maybe in this thread or somewhere else I said that I like trying different toppers for my coatings. Currently 22PLE HPC applied this past July and before that Cancoat for two years. I like trying new things and sometimes the product doesn't meet my expectations. Kamikaze Overcoat v3.1 has been my go to, but I've also tried Polish Angel High Gloss, Sonax BSD, Diamond ProTech Quick Body, Gtechniq c2v3, and others. I've never wanted to try Griot's 3-in-1 because while it's durable it's hydrophobics are not up to par for me. Sonax's new ceramic detailer looks to be excellent and I'll admit to overlooking it.
