Gyeon CanCoat is a unique product, which perhaps is the source of its positive and negative feedback. Without going into the specifics or the source of controversy, I have witnessed many critical reviews missing context or being biased in variables tested. That is not to say the critiques are without merit.
Members and I of the detailing community cringe when we hear of any spray on product that has the name ‘ceramic’, ‘coat’, or ‘SI02 in it’. We have seen these (maintenance spray) products sold and detailing services with the application of these products offered with the blatantly misleading implication the consumer is getting comparable protection to a true ceramic coating.
Though not quite putting Gyeon CanCoat in the category of a traditional coating, I do not think it is fair or accurate at all to compare CanCoat to a sealant or a wax. With respect to the mixed reviews that I have seen on social media, the user error in the way the car is prepped prior and post application of CanCoat is the cause of these issues.
CanCoat applied in not the most ideal scenarios can serve as an exceptionally strong sealant. But applied properly like a coating it can act like a hybrid coating (9 months chemical resistance) or in two layers pass as an actual coating.
A lot of conclusions about this product from reviews stated as such, ‘if a product is really that durable (while being easier to apply) it shouldn’t need that extra time in a dry environment to set.’ Often the opposite is often the case. In brief, if you want CanCoat to act like a coating, prep and pamper it like a coating. If you treat it like a spray on wax it will act like one. That extra time the product has to set allows for an increase in chemical resistance.
My suggestion for those who want to maximize the durability (1+ year protection) with coating qualities close to other traditional coatings, 2 things I will recommend. Apply in two layers. Also prep before and after like a traditional coating. Usually, 24 hours is the minimum time for a coating to be sheltered in a dry climate-controlled environment, which includes avoiding exposure to moisture of any kind. A minimum of 12 hours for CanCoat is recommended (24 hours for certainty) of avoiding moisture. Proper cure time for most coatings also means not washing the car for a week. This is also another problem when you see reviews of products tested the day of or immediately with harsh chemicals, comparing it with sealants. Like all coatings, throw away your microfiber towels post application.
An alternative to two layers that I have not tested but have heard great reviews on is using Gyeon Primer polish to prep a car for CanCoat.
I have heard of some individuals using CanCoat as a drying aid, with even less durability being the tradeoff. Although I have not personally pushed this product to those limits yet, it is a testament to the versatility of this product.
If you are in not so ideal circumstances or have not applied a coating, this is a good product to try.
Moments after applying CanCoat to this BMW it had begun to rain. I immediately began to see very good hydrophobic behavior (water beading).
Although paint correction on a fully decontaminated surface is the main course in approving the aesthetics of your paint, I have noticed an amplification in the look of the paint after using CanCoat. Gyeon CanCoat has the ‘glass like gloss’ look a coating provides as seen below with this Audi RS5.
