GyeonPrep Redefined 4 L - Pre Coating Car Prep Spray | Ceramic Coating Prep Spray for Proper Ceramic Coating Application

This surface prep is probably one of the best I have ever used. It's absolutely better than chemical guys. The thing that I dislike the most is the price. This is very very very expensive, but for the quality of the product, it's well worth it. Every time I use the product and depress the spray nozzle, it hurts me a little inside, haha.However, if you want to be sure your surface is prepped and cleaned before using adhesion promoter, putting on a ceramic coat, PPF, or anytime you are doing anything to your vehicle surface or any surface in general, this product will absolutely ensure it is clean, free of contaminants, and ready for whatever application you are trying to perform. Spend the extra money for this surface prep and save yourself headaches down the road. This is a premium product and it ensures you get the job done right.

I compared numerous similar products as well as plain ol’ alcohol. In the end, I decided on the Gyeon Quartz Prep.Very easy to use, no nasty smell and did a great job removing residues from the paint surface.I completed a multi-step detail including claying, polishing, and protecting. Used the Gyeon Quartz Prep after claying and again after polishing to remove residue that was left behind.This went on and wiped off quickly and easily. It removed all residue from the paint leaving behind a clean surface for final ceramic finish. A little goes a long way!Will definitely continue using.

Like most Gyeon products it performs excellent. I also love their clay lube as learned from Pan The Organizer. Gyeon is a semi-pro brand from Korea, which means the quality of products is top tier but also not ultra expensive and can be used by normal people too.This alcohol panel wipe smells great. And dries with no residue and removes anything still left on your paint after washing, claying, etc before sealants or coatings.I don't have alot of other panel wipes to compare to as this is my first, so maybe they all work as well, but this smells great and works perfectly. I just wish it was a little cheaper more in line with P&S Detailing pricing.

I used this before my ceramic coat. It worked great!Now I have been using it as window cleaner and it leaves a beautiful streak free shine.

Seems to do a nice job of removing polishing residue and old wax/sealants from the paint, but again so does the alternative of alcohol and water. The product smells nice, has a great presentation, and nice sprayer (same the one Car Pro uses). It only takes a few sprays to wipe down a panel. It doesn't necessarily make removing polish from a panel easier. But after wiping with a towel and spraying this on the panel you have a tactile sense that the panel was cleaned. I also find that spraying this on after wiping off the polish is the most economical way of using it. If you are willing to spend the 15 bucks it is definitely an improvement over IPA, but not a massive one by any stretch. I do think if you are applying Coating this is must. Even if you are just using wax, spraying this on and cleaning the panel seems to extend LSP durability and mitigates any concerns over product compatibility.

Very easy to apply and the brilliance comes out immediately. Well worth the money and if you are as finicky, as I am, you will truly enjoy the product.!
