Challenges with Gyeon Cancoat

[dmboone25]

What’s your towel situation? Did you use your same trusty towels to apply & remove? Or did you use brand new virgin towels? Same question as far the prep wipe.

For the reapplication, I used brand new towels - a short pile microfiber to apply on one side, buff on the other. Then I had a second plush towel for the final buff.

Like I said, the first few washes (4 I would guess), the beading action was as advertised, in that it was awesome. Then, it started losing steam over the next few washes and now is really slow to dissipate off some areas. Still working well in others, but my application process was the same over the entire car, so I’m just perplexed.

Where do you live? Perhaps there’s alot of air pollution where you’re at? I know in the area of Los Angeles where I’m at its very bad with smog, fallout, surrounded by refineries, etc… Typical lsp’s are lucky to last just over a month and that’s being optimistic. I’d be shocked if Cancoat could last 2 months here. I hope to test it 1 day. I’d bet good money it won’t make it.

When applying a coating/coating lite, most Manufacturers recommend a decon wash.

Tar remover if needed

Iron remover

A decon soap, alkaline or acidic. I do both alkaline then acidic then PH neutral.

Then a paint prep.

A normal wash may not remove all Impurities from the paint. Especially in the problem areas.

Short of polishing this is process most if not all recommend.

You may even find that if you had decon washed before recoating it may have “woken up” the coating by removing traffic film and contamination that a normal wash couldn’t.

I live in the north Dallas area - there’s definitely a lot of pollen in the air, not sure about other pollution. This particular car does sit outside, but gets washed once a week. The whole reason I tried Cancoat is that Wetcoat wasn’t really sticking either. I’ve used that product forever and haven’t had this issue before….

I just did a plain wash with foam and bathe before reapplying.

It probably did not bond with just this as prep. At a minimum a panel wipe should be used.

Totally disregarding his OP, where he clearly prepped to the T and had the same result.^

 

[dmboone25]

I really tried to prep well. I might have missed the mark on that front.

I’ve just not had the experience that seems to be the norm for this product. I use a lot of Gyeon products so it’s not like I’m biased against the brand. It just doesn’t last nearly as long for me as it’s supposed to. I didn’t find it easy to work with either - it’s really grabby and easy to leave those shadows or high spots all over the place. I have no idea how anyone could do their entire car in 20 minutes. More like 2 hours.

My point being, if this is supposed to be so easy, then why do all these other factors matter? If I am supposed to be able to just spray it on, wipe it off, and move on, why does it seem to fail after 5 or 6 washes?

That’s pretty much my point. It’s contradictory to say that this is supposed to be a really easy product to use, and yet the towel I used or whether or not I used a panel wipe prior to application could be fatal to its overall effectiveness? That’s just bizarre to me.

I saw that you used ceramic detailer every wash. This is not going to be removed with Bathe or even a panel wipe. It is sitting in between the CanCoat and the previous layer of Cancoat. It is going to need a decon wash to remove the ceramic detailer chemically.

I don't know how old your bottle is but CanCoat will become unusable after a few months once it is opened. I applied it to my brothers compact SUV in 15 minutes with the towel as an applicator. If you are getting high spots you are using too much product.

My review is on the forum here for when I applied CanCoat Evo.

I’m sure this is sacrilegious to some, but the older I get, (73) the easier I need things to be. Last week I did my brand new BMW 228i GranCoupe with CanCoat. The paint was in great shape being new, (after I ran the baggy test), so all I did was spray and wipe down each panel with 50-50 IPA, and then put on the CanCoat, it worked perfectly. I Put it on with spraying a microfiber brick, then immediately followed with a fresh microfiber. No pics, the car is now up north and I'm back in Fl.

No i saw it but obviously something didn’t bond. To just apply over whatever caused it to fail, just gonna do same thing.

Polish was already done to better the paint… so trying to prep again to remove what was making it fail.

OP, you said was tacky on removal? How long was it open?

Sorry your experience sucked with it but your experience is an outlier.

it is a pretty easy product for almost everyone here who used it. Your experience is not the norm. Just trying to help you troubleshoot.

The notion of Can Coat being "easy" to apply relates to the simpler application method compared to a traditional ceramic coating, ie a spraying into a towel and a wipe on/wipe off process, compared to the more methodical liquid droplets onto an applicator block and observing flashing times before removal. In that respect, Can Coat is extremely easy to use.

However, it is still a ceramic coating and therefore requires appropriate preparation to ensure a correct bond to the paint, ie tar and iron removal, claying (if needed) and polishing (if needed), all followed by an IPA/Prep spray wipe down. Skip these steps, the performance of the coating will be compromised.

Definitely an outlier.

The other way to look at it is sometimes you just don’t get the results you want for whatever reason. I’ve bought products that I’ve used before and didn’t get the same results, I’ve tried new products that looked promising and I just didn’t enjoy them. I wouldn’t dwell on it and it’s ok to just move on

I was referring to the Guz reply.

Cancoat is not that easy to use IME either but for me it has proven to be stout but nothing extraordinary.

However, if the bottle of liquid fails in 2 years i wouldn't consider buying another one. I have a bottle of essence+ to try next for a stand alone sealant. Should be interesting.

But i agree it's not "easy" to use. It stinks, clogs up sprayers, grabby wipe off and it will leave high spots like any coating. It works but i don't think it's in the "easy" category sorry folks lol

Caveat: This is all relative. In a garage, cancoat would be pretty straight forward. But again easy would not be a word i would use to describe cancoat lol

Update! I finally got to give my car a decent wash and the self cleaning of cancoat or the magic of my polisher must have affected something lol

I just pre-treated some areas with a light acidic/alkaline homebrew, low pressure rinse from the town and a rinseless wash. I still don't understand where all the dirt went. It's not a daily driver but sits outside with very little washes - was basically the first half decent wash i done on my car since i applied cancoat last oct.

Nothing makes cleaning easier than a coating…

i found it to be a really gratifying experience...ya gotta have that detailing bug to feel this way I guess....but when I cleaned my bike for the first time after CanCoat...right away I realized something....I am able to more gently wash my bike and return it to pretty damn near close to how it looked right after the detail, in way less time
