Gyeon quartz Q2 LeatherShield or Q2 LeatherCoat? Which One and Whyby Jeff McEachran
This article is written by Jeff McEachran, National Brand Manager for GYEON quartz USA and owner of Denver Auto Shield in Denver, Colorado.
The best way to start this conversation is to take a moment and think about what we are trying to achieve in coating modern leather seats and interior pieces. We apply long-term protective coatings to any surface to prevent or minimize the slow degradation of those surfaces due to exposure to daily life. In modern leather seats, in particular, we are looking to keep the surface protected from UV damage (drying and fading), reduce the amount of contaminant it absorbs (skin oils and dirt that create the “shiny” leather), reduce “die transfer” (the die of a new pair of jeans or pants rubbing off on the leather), and reduce the cracking or breakdown of the leather over time (usually seen in the side bolster).
Both Gyeon quartz Q2 LeatherShield and Q2 LeatherCoat solve all of the problems listed above, just in slightly different ways.
Both products are designed for modern leather, leaving an invisible layer that does not affect the color, look, or feel of the surface. Both products are hydrophobic and repel both dirt and liquids. Both provide strong protection from UV rays. Both create a very slick surface to protect against the wearing down of the leather material as well as die transfer.
The difference is in the chemical makeup of each, their application, and their intended durability.
Let’s assume your leather has already been cleaned with a high-quality leather cleaner like Q²M LeatherCleaner.
Q2 LeatherCoat is water based, using a resin as its main active ingredient to provide UV protection, slickness, and its hydrophobic properties. Q2 LeatherCoat is very fast and easy to install and is designed to last up to 3 months.
Once the leather is clean, simply spray one or two sprays of Q2 LeatherCoat on to a high-quality microfiber towel and work it into the surface.
Q2 LeatherCoat is great for the DIY user who wants a fast and simple way to protect their leather and is fine applying it a few times a year. From a service perspective, Q2 LeatherCoat is great to recommend to clients who may have chosen your long-term leather protection service as a maintenance upkeep product. It can be used over Q2 LeatherShield as needed.
Q2 LeatherShield is your long-term option. It is based on Silica Dioxide, requires a more “formal” coating application and is designed to last upwards of one year. Leather is a tough surface on which to mark durability, as it is solely based on use and abrasion. For example, the rear seat of a car that doesn’t see much action will last much longer than the driver’s seat.
Q2 LeatherShield is very unique in its application. Again, we want a well prepared and clean surface. Apply a generous amount of Q2 LeatherShield on to the Suede Applicator. Work into a controlled area. Q2 LeatherShield does not need to be immediately “wiped off”. The product will appear “wet” on the leather. Allow it to dwell for up to 10 minutes and permeate the pores of the seat. After 5-10 minutes depending on working environment, wipe off any remaining product.
I hope this sheds some light on to which leather specific product from Gyeon quartz may be best for you! I’m glad to answer any questions in the comments below.
Great write and explanation of both products. I have used both and they both work very well. Good to know that leather coat plays well with leather shield. I may have to try this on my daily driver that has leather shield.
Awesome! Great to hear.
The Q2 leather coat requires for leather to be clean, does the Q2 leather shield qualify to clean the leather sufficiently before applying leather shield ? Or do I need another special cleaning product?
Using this system do you need to apply a leather conditioner at all to moisturize the leather? I have a 2010 Infiniti so modern leather. Reading online I get conflicting information regarding whether you want to condition modern leather seats in addition to coating them or just skip conditioner and apply a coating only?
Thanks – i think i will go with Leather Coat
Which one of your products is highly recommended for white leather car seats?? How long will the product last after applying it? Does it repel dye transfer? Please advise.
On White leather seats, I prefer LeatherCoat. I would be wanting to clean and touch up the seats more regularly than a dark finish. So cleaning as needed with LeatherCleaner and a quick and easy re application of LeatherCoat is the way I would go.
Can leather shield be applied to vinyl surfaces??
Nathanael – Yes it can! Leather Shield can be applied to leather and vinyl surfaces.
Can I use the leather shield on Toyota softex leather?
You should be able to use Leather Shield with no problems. Direct from the Gyeon site it says “Q² LeatherShield is an advanced, SiO₂ based formula, specially developed for all types of modern automotive leather upholstery” and “Q² LeatherShield is suitable for every type of leather produced to date and does not change the finish of your upholstery”. I always recommend testing a small spot with any product if you’re still worried after reading the instructions carefully. If you have any other questions please let us know.
