GYEON Q²M Wet Coat Full Product Review

Gyeon Q²M Wet Coat took the detailing world by storm a few years ago. After having done a bit of research into the product, I decided to go ahead and purchase it to see if it really lived up to the hype.

In this review, I’ll be going through all the pros and cons of this method of paint protection and giving you my overall recommendation as to whether it’s worth purchasing. Here’s my take after using the product for over a year.

What is Gyeon Q²M Wet Coat?

Gyeon Q²M Wet Coat is a spray and rinse sealant that is applied to a wet car, and rinsed off immediately to leave behind a strong layer of protection. It can be used as a stand-alone product or to top up existing sealants or ceramic coatings, and offers up to 12 weeks durability.

I’ll be breaking this review down into the uses, application method, protection level, finish and the pros/ cons. If you want to sit back and relax, then check out my YouTube review below.

What Can Gyeon Q²M Wet Coat Be Used For?

Unlike traditional waxes and sealants, Wet Coat can be applied to all exterior surfaces to provide a durable layer of protection. This includes:

  • Paintwork
  • Trim
  • Glass
  • Alloys

It’s versatility is one of my favourite things about the product. It really cuts down the time it takes to protect the entire vehicle, and saves you having to buy a product for each specific area of the car.

How to Use It

Gyeon Wet Coat is a “spray and rinse sealant”. You can apply the product according to the following instructions:

Method 1

  • Wash the car and rinse away the shampoo. Do not dry the car.
  • Shake the bottle well before use.
  • Spray the product onto a panel and immediately rinse away with pressure.
  • Repeat this process one panel at a time until you have coated the entire car.
  • Dry the car as normal.

The entire process is very straightforward and quick. It usually takes me around 2-3 minutes to protect my entire car using this method.

However, I have discovered a more effective way of applying the product which improves the performance and durability. Here’s how:

Method 2

  • Spray the product onto a clean and damp microfiber wash mitt 2-3 times.
  • Immediately spread the product across a single panel and ensure even coverage.
  • Rinse straight-away.
  • Repeat the process one panel at a time, around the entire car.
  • Dry the car as normal.

This method does take slightly longer, so usually just over 5 minutes, but that’s still really quick! I’ve noticed an increase in water repellency and better durability using this technique.

I’ve compared these two application processes on my YouTube channel.

Whichever method you go for, there are a few rules to keep in mind to avoid streaks and product spots.

  • Never apply this product when the panels are hot/warm or in direct sunlight.
  • Work one panel at a time, don’t apply it to the entire car and rinse. Always rinse immediately after application to a section.
  • Make sure the panel is wet before applying.
  • Use the product sparingly. 2-3 sprays is more than enough per panel.

Slickness and Gloss

This product leaves a nice clean finish behind, that has a decent level of slickness to prevent dirt and dust sticking to the paintwork. It is not the glossiest product I’ve ever used, and won’t completely transform the finish of your car. To be honest, I’ve not tried many paint protection products capable of this.

Here’s how my car looked after applying Wet Coat.

As you can see, a lot of the “gloss” comes from the lighting. So try not to get hung up on it when you are choosing a method of paint protection. Keep the paint in good condition and the gloss will take care of itself!


Gyeon claim that the product provides 3 months protection, or up to 12 washes. Personally, I notice a sharp decline in the performance after around 6 weeks.

Granted, my car is stored outside and driven daily in rainy British weather, so it does get a bit more abuse than a lot of other vehicles. However, I think you should be prepared to apply the product at least every couple of months in order to maintain the performance and protection.

Protection Level and Hydrophobicity

Being a ceramic-infused product, you’d expect a good level of protection. I think this product does really deliver in terms of water repellency and shielding your car from the elements.

Dirt and dust definitely find it harder to stick to the vehicle, preventing the build up of contaminants that can attack the finish. It also provides a good level of resistance against water spots, which can be easily wiped off when washing without leaving any traces behind.

To put the hydrophobicity level into context, here are some photos of the water behaviour.

Pros and Cons

Like with every paint protection product on the market, there are advantages and disadvantages to this one too. Here are the main pluses and minuses from my experience.

Costs less than $1/ applicationNot as durable as a traditional sealant
Excellent water behaviourNo noticeable boost in gloss
Can be applied to all surfacesCannot be applied in direct sunlight
Very quick application methodRequires a pressure washer to apply

Is It Worth Buying?

If you’re after a really fast and solid level of protection for all exterior surfaces of your car, then you’ll struggle to find a better alternative. It’s ridiculously quick to apply, it’s cost effective and the water behaviour is impressive too.

If you’re an enthusiast with a bit more time on your hands, then you may prefer a traditional wax or sealant which can deliver better gloss and durability.

I’m lucky to have a lot of detailing products in my collection, but this is a product I’d really struggle to be without. I use it on my own vehicle primarily on the alloys, or to boost existing protection, and I also use it on my friend’s and family’s cars as stand-alone protection when I’m pushed for time.

Overall, it’s an impressive product that does live up to the hype.
