Just venting out here . I just did a " 3 year ceramic coating" on my 2019 Audi sportback , no my first ceramic coating , but my second one with Gyeon products. I went through the whole process , acidic wash , iron remover, clay , polish , and eraser to finish off. I had previously put on Gyeon Pure evo on this same Audi and after a week I had to re-polish the hood area because the water spots were not coming off . Also the ceramic coating itself " failed" after 6 months , it was hydrophobic at first but after a while it was mehh . It was removed from my car after a year. I spend the winter playing around with waxes and sealants without any issues .
I had used car pro essence as a polish on my first installation of Gyeon pure , so I thought maybe the protection left behind by essence was not compatible with Gyeon pure . This time around I decided to put Gyeon Mohs on my Audi , also I used car pro reflect that leaves not protection behind to prevent any interactions issues between the two brands
The coating process itself was a breeze, the products goes on easy , flashes quite fast ( 30 seconds @ 20 degrees Celsius) and the removal is quite easy , very slick for a coating. I did 2 layers of mohs , I took the car outside to check for high spots and I only saw one which was corrected the same day . The car looked great . I also applied Gyeon cure which was part of the kit after 12 hours to prevent any water spotting issues for 2 weeks . Car was inside the garage for 3 days just to make sure the product had time to cure.
This is when the nightmare happened , again , I can't wash the car for 2 weeks according to Gyeon , so after 3 days I had to leave the car outside and it rained , as soon as I came out of my house in the am I can see the water spots from the rain, these spots looked different though , like a crystal/ rainbowish look engraved on my car , not the same look as the water spots I get with my other sealants and waxes I have been using. I didn't think much of it but I had the feeling that it was going to be a problem ... I would usually wash the car after work if it had rain , but I left it for a few more days . It was a week where it rain sporadically.
Fast forward to 10 days after install and I go for my first wash , as suspected the water spots do not come out , no matter what . I tried to polish a little area to see how bad it is and luckily enough polishing is removing the water spots. This is just like last year when I applied Gyeon Cure on this car, probably worst because now its all over the car instead of just the hood. Im removing this garbage from my car tomorrow , repolishing the whole car again and putting a wax on it.
My conclusion is that this product sucks , it cant even prevent water spotting from rain , I had other waxes and sealants on this same audi for the last 6 months, it has rain and snow and I never had an issue with water spotting , they came out after the wash no problem , but for some reason Gyeon cure, pure and mohs attract water somehow that it leaves water spotting more noticeable and it doesnt come out with a regular wash , and this is not water spotting from a sprinkle , its from rain
I m pretty much done with ceramic coatings too , every ceramic coating that I have put on always requires a sealant on top to prevent water spotting , so whats the point really, if you are masking the properties of the ceramic coating with a sealant , may as well just put a sealant on top without a ceramic coating. Looks wise , I ve been playing around with waxes and sealants the past 6 months and they actually do look better for me ...
I have better luck with car pro ceramic coatings but I dont think I would do it again
anyways just ranting today ...
