From my experience, I wouldn't use CanCoat as a QD. I like my QD's to be a simple spray on/wipe off product to get rid of random smudges, bird bombs, or water spots after a wash. Like Guz mentioned, it doesn't have any cleaning ability and it isn't as easy to use as other QD sprays. Even diluted 1:1 I had to be careful not to get any streaking. At full strength it was even more of a challenge.
Is Cure a good topper to use monthly to boost CanCoat? Yes! I noticed it really improved the gloss of CanCoat, which I thought looked pretty good already. Did it extend the life of the CanCoat? Maybe. I got 12 months out of it and that might have been due to frequent applications of Cure...or maybe not. CanCoat is a great product all by itself.
When I think QD, I think of a product that is pretty easy to use.
I love CanCoat and I'm really glad I used it as the LSP on my bike. It is a beautiful slick finish, especially over a properly corrected surface. I am not throwing shade at the product at all and wouldn't discourage someone from trying it, but when I think of how I had to use CanCoat properly, and how I've used any detailer I've ever used, the difference in application is very different.
CanCoat needs to go on quick, and it needs to come off nearly as quickly. If not, it can start to get grabby or flash.
I made a mistake applying the product when putting it on my bike. I'd done a practice run on my truck, but the panels were very flat and easy to segment and apply a uniform coat on the surface. The curvy rear fender of my bike needed a little different strategy. After I finished, i took an inspection light to the fender and found a fairly cloudy blotch. When lightly running a MF cloth over the fender, it felt slick and slippery, and looked great, except for that spot which was slightly cloudy and a bit of a grabby feeling. My next step was a mistake. I tried to buff out the cloudy part with a bit of elbow grease and a MF towel. Rookie mistake. Took the light to it and saw that my effort had reintroduced swirling to an already corrected panel....nothing crazy, but enough where I could see that I'd marred the surface with the MF cloth in my attempt to 'fix' CanCoat.
I did a quick spot correction on the swirling, gave a little more attention to a couple of other areas while I was at it, and then did a full polish with Wolfgang's Finishing Glaze to make sure all of the CanCoat was removed.
With the second shot, I did it right and then used it as a strategy for the rest of the bike. Bottom line, ya gotta work quick with CanCoat.
All of this to make the point.....way different than a QD. Really great product thought. I'm a huge fan of CanCoat.
BTW, I've been using ECH2O to maintain it. 1:10 dilution. Does a great job of cleaning it up and adding a bit to the gloss. For a bigger vehicle, I might dilute it a bit more, but with the smaller surface area to cover on the bike, the stronger mix works for both cleaning it up and as a QD.
