Usage and durability claims from Gyeon`s Site
Brief background on this particular product. This was announced back in November at SEMA. It is a new product offering from Gyeon for 2017.
As the above product description states, this is an Si02 leather coating. It`s similar to Cquartz Leather Coating in terms of both being quartz based coatings designed to work with leather.
I had pre-ordered it from a different site and not thru Autopia. I am not sure if it will be sold through Autopia.
It comes in a really nice and attractive package. Similar to can coat.
Here are the what the product claims to do.
Directions clearly stated on the package and on the bottle. Easier to read on the box instead of the clear bottle.
The amount included is 50 ml for $50. More than the cquartz leather coating which is 30 ml for $70. The 50 ml of cquartz leather coating is $95.
Included contents except the costco towel.
Per Gyeon`s site
I was missing two suede cloths if this kit is supposed to come with 6. Other than that I received everything.
I am going to have to refer to the video for application. The product goes on wet but as it is flashing off the surface it goes clear. I followed the directions as the leather coating is left to flash off. No darkening effect noticed. The leather looks untouched in terms of looks just as the product description states.
Prior to applying it, I cleaned the leather with Meguiar`s D181 followed by a towel damp with water to remove any residue left behind by the leather cleaner. Essentially the same process that I did for cquartz leather coating.

Due to me not knowing how the coating works and whether or not it can get wet right away, I let it sit overnight to cure. Cquartz leather coating recommends to not get the coated surface wet for 4 hours as well as the coating fully curing in 3 days. I treated Gyeon Leather shield the same.
The next day I used the included pipette to deposit water onto the leather surface to see if the surface had become hydrophobic. I also misted it with a spray bottle (water in the spray bottle) as seen in the part 2 video. The only reason I show this is to display whether or not the surface tension has changed. No other reason. Plus we all enjoy seeing beading
.
Here are the results of depositing water onto the leather surface. The water was easily wiped off and left no water spots behind.
Overall I enjoyed using this leather coating. Initial impressions is that it is a very good competitor to Cquartz Leather Coating. It helps that it is cost less with more in quantity compared to cquartz leather. Making leather shield more attractive. Long term performance will be the telling sign of whether or not it is a direct competitor. I will update the progress on it as I applied it to all the seats other than the driver`s seat as I have a test for another leather protectant going. Once that is done I will be coating the driver`s seat.
The hydrophobic properties it leaves behind is very good. Similar to cquatrz leather. The surface between both coatings feels very similar as well. Not super slick but just enough to tell that there is something on the surface.
One thing I liked more with Gyeon Leather Shield is that a little product goes a long way. Much more than cquartz leather. I found it to be a little easier to work with as well as spreading out better.
Gyeon only recommends one coat. I was able to get a in touch with Jeff the rep from Gyeon to answer my question on multiple coats. He confirmed that one layer is all that is needed but that it can be layered for multiple coats. Thanks Jeff for getting back to me.
I also like that it does not need to be buffed off as the product is designed to flash off. It`s optional to buff off. CarPro recommends buffing off any excess 2-3 mins after applying cquartz leather. One thing that worried me is that leather shield appeared to leave high spots as it was drying. I was so tempted to buff it off but I left alone as shown in the video and all was well. No high spots or streaking.
The Gyeon site states the average consumption is 40 ml per vehicle. On my 99 Pontiac Grand Prix, I hardly used any of it. The bottle is about 3/4`s full. The front and rear seats are leather as well as portions of the door panel and the shift boot. So I have plenty to coat a couple more vehicles.
Based on initial impressions, I would give Gyeon Leather Shield the thumbs up. If Autopia decides to carry it, I would recommend others to try it out.
Before I forget this product is meant to protect and not restore.
Application video
Water Repellent Test
The applicator did not get hard or stiffen up as the coating dried overnight. Similar to cquartz leather. I would say this is by design so that it flexes with the leather material.
Thanks for reading and enjoy the videos. Future updates for long term durability testing will be available as time goes on.
