Amazing
June 18, 2020
I prepped the car with iron remover, synthetic clay, correcting polish, perfectly polish, and panel prep before applying CSL and EXO.
Crystal Serum Light went on very easy and I only used about a third of the bottle on my s2000. I used microfiber suede and the carpro block to apply the CSL. This technique made it easier to control the amount applied as well as evenly spread the coating over all surfaces. After just the CSL the paint was very smooth and shiny.
I followed the same process to apply two coats of EXO. The paint didn't look much different after this but it's more about protecting the CSL in my mind.
The last step for me was to top the cured EXO with bead maker. I see this as a pretty cheap and easy way to add additional protection, shine, and slickness to the finish.
Happy detailing!

Best coating used yet
March 14, 2022
This is by far the best coating that I have used in about 12 years of detailing. Started off with using CQuarts, moved into Gyeon Mohs, then tried CQuarts with the Skin and their other for ppf. Finally decided to try C1 from Gtechniq and found it was very similar to the Cquarts that i always found myself going back to.
Living in the New Orleans area its always hot, humid and pretty much worst conditions for trying to use these products. Had a long time client receive his new 2022 BMW M3 and decided to try the Gtechniq products again. This time using CSL and Exo we were both blown away. CSL doesn't smear any take a bunch of effort to level like the other products always have. Exo has been easy to use as well. Feel like since switching to this duo I have done more coatings in three months than I typically do in a year. Do one car and get the neighbors new car the next week. BEST COATING EVER!

Easy to apply and looks fantastic
December 19, 2021
After looking at several reviews, I decided to purchase this coating and install it on a white Mercedes. I did 1 layer of CSL and 2 layers of EXO. Both were easy to install and have long working times. I used 3 leveling towels for each step to ensure no high spots. Results were outstanding. I will be using g this combo again!
ProsLong working time, easy to level, and great shine.
ConsNot a real con, but according to their instructions you need to start layering EXO over CSL within 12 hours. I started CSL at night and then had to wait for it to get warm enough in the morning to install EXO. I should just started in the morning with CSL.
