Coated the glass on two smallish cars with this today ASX & Lancer both previously coated with two different glass coatings, clayed and steel wooled all the glass the polished then cleaned with IPA then used the Gyeon cleanse with the hand block provided.
Application was easy enough and I would recommend for a first time user as Gyeon have a good video that shows all the steps a lot of glass coatings are very vague on how to apply(Carpro Flyby Forte for example), I've used around 4-5 different glass coatings before and this would be up in the top with the easiest to apply, I coated both windscreens and rear windows with 3 layers and side windows with 1 on one car and 2 on the other out of one bottle, I was shocked I was using what I thought was alot and was prepared to use 2 bottles.
Wipe off was pretty tacky not going to lie I don't think you need to wait 15 minutes It was cold today 13degrees and seemed to finish flashing around 5-10 minutes but if a first timer I would stick to the 15 Minutes
I used coating removal style towels for initial wipe off then used a waffle weave for final levelling I would 100% recommend using a waffle weave towel for final wipe down.
In all honesty there are other glass coatings on the market that are alot quicker to flash over and take less time to apply but that can also be a bad thing if your a beginner at coatings
Will post another review once it has cured and tested it out in the wet and cleaned them so far happy, much easier to apply then some others abit time consuming took around 2 hours doing two cars side by side only time will tell on durability
