Gyeon Primer 1000ml – SiO2 Coating for Paint Prep, Gloss & Smooth Finish – Pre-Coat Polish for Ceramic Coats Easy to Apply – Car Detailing Surface Enhancer – Increases Bonding & Shine, Polish

This product is excellent as the preapplication to the ceramic coat. I highly recommend this product. It replaces other products that I have used. Purchase the 1000 ml.

Easy to use. Just don’t overwork it. Use it for what it’s designed for, priming and final polishing before whatever coating you’re going to use.

This product has been extremely difficult to acquire via Amazon. Having quite a bit of amazon funds to burn I waited for this to be restocked. In my haste to scurry and purchase this before it sold out again I was blinded by “restock syndrome” and completely failed to notice the size of this bottle. Update, it’s tiny. Without tax for ease of calculations It’s $33.90 normal price on Amazon. Divide that by how much you get, 4oz, and that breaks down to $8.46 an oz. Doing the math with a comparable product, Carpro Essence Primer, and Essence selling for $27.99 without tax divided by 8oz size and you get $3.50 an oz. Gyeon’s primer may be a great product but paying not only double a comparable product for this ant sized bottle but 2.4 times the price…is it worth it? Our goal is to final polish and remove light scratches with an added benefit of priming the surface. At the end of the day, numbers ie:price still rule the game. Lets say both products are equal in in outstanding performance, ability to create a beautiful gloss but more importantly amount required to cover the same square footage of paint, less cost for the same features per oz means more customers per bottle. Customer satisfaction while money making our driving force. Note: I am but a lonely detailer and not a mathematician therefore, adjust your expectations of my calculamatizations accordingly, but rough numbers are correct. Today is 7/9/2024. This review will be updated as product is used. Gyeon makes great stuff, usually at a fair price so initial review is 4 star. However, the star rating will be adjusted as required. Stay tuned for updates.

We have been using this before ceramics for some time now. Only use this if you want an "out of this world shine". My pix above will show you that. My clients call it "the moving mirror maker".

Works great with all coatings.

I like the product but at the current price for a sample bottle is just wrong. I bought the larger bottle but the smaller size is way to much.

I’m hoping the other detailers KNOW what this is used for. This product is used as a FINAL polish before Ceramic Coating. It’s a quality prep polish for those kind of jobs. Although besides the great quality, the price is way to high for such a small product.

too abrasive for a new rig, using "PS-21 polish" like a charm, product is not for new vehicles (scratched demo test surface)..

Excellent

Great for getting that jewelling finish before adding any coating. Easy to use and has very long work time. Only thing is, that it has minimal cut. It's meant only refine the finish.

This is a great polish with a good level of cut for use prior to a ceramic coating. I used this on my new Audi which had some light swirling and paint defects which this managed to remove rather easily. This polish also helps the ceramic coating bond to the surface allowing the coating to be easily laid down
