This is my second use of CSL. The first time results were OK but not as good as I wanted. The second time I used a foam bar and suede cloth for application and it worked much better. I also buffed a larger area with a second MF each time I applied a 2x2 area. Covering a much larger area than the 2x2 with the second MF really helped. Using the foam bar and suede cloth also helped me cut down the amount of CSL I used so I had a half-bottle left over. Also I used Essence to finish prep. Results were excellent!

I'm very impressed with CSL. I put it on my Audi S6 phantom black pearl paint over a year ago and it's still holding up great, water glides right off. Makes car washes much easier. I did top off with EXO but not really sure it was needed. I also apply a sealant ~ 3 months, usually Black Fire Wet Diamond or Jescar Powerlock.

You need to make sure and follow the directions. There were 2 small areas where CSL dried that I didn't see until days later. It doesn't come off without some elbow grease. A few months later, I broke out my DA polisher and removed from the small area.
Used the entire 30ml bottle on my sedan.

My wife may get a new car soon and the first thing I will do (hoping no major correction) is to apply CSL!

It is all in the prep. You MUST have near perfect or perfect paint to get a proper bond and excellent results out of any coating, CSL is no different. What IS different is the ease of application and removal. Not the greatest beading, but it sheets like crazy and makes for an incredibly fast and easy wash process for years to come. Top with EXO for crazy beading or maintain with C2V3. Top notch product, a 30ml bottle used on an average size sedan will leave you with enough left over to do a small car or if you missed a spot, touch up and then some.

Decided to give CSL a shot since I really like their G4 trim coating. All I can say is wow, they have made applying a coating easy...as long as YOU follow the directions. I deconned, corrected, and wiped down with Eraser.
With good lighting, multiple cloths for removal and application, and proper protections, it was pretty straightforward and easy. It took me about and hour and 15 minutes from start to finish.
The Gloss and slickness are pretty amazing. Again, just follow the manufacturer's instructions. I managed over three years of protection with my last consumer grade coating so if I get that with CSL, this will be my new favorite.
I did use the small white pad that came with the coating but dropped it after a couple of panels. I switched over to the foam block and suede cloth and had no issues.

In my opinion this is pound for pound the best consumer available coating on the market. It is affordable, has great durability and when topped with EXO, it looks amazing. Application is smooth and easy. I use the blue foam applicator from Optimum because it takes much less product. Wipe off is just as easy and when done I like that I don't have to worry about the towels hardening. Until technology delivers a better coating this will be my go to coating.

This was my first venture into paint coatings and my initial impression is that this stuff is awesome! I applied it to my brand new SUV after polishing the paint and using the panel wipe to remove polishing oils. The application was very straightforward and I had no problem leveling and buffing off the residue. My color is dark blue and it looks like the application is flawless. The paint has a nice wet look and the slickness is really nice to the touch. Haven't washed it yet so I can't comment much other than initial impression is very positive. I hope it holds up. Tip: get the 50ml if you have a larger car or SUV (especially if you will do extra surfaces like door jambs). I almost ran out before completing my job.

Very nice results! Just have to be patient in the preparation of the paint and following the directions exactly.

Applied in a 55 degree warehouse, easy as could be. Used the foam block/suede cloth applicator as opposed to the included one, seemed to go quite far. 2014 Ford E250 Econoline panel van used maybe 30ml of the 50ml bottle. Wiped on in crosshatch pattern, pretty much wiped right off. Very slick feel...added C2v3 Crystal Crystal after letting cure for an hour or 2, should help with water behavior. All in all a definite winner for ease of use, wide application temp range from 38F to 80F makes it an early 'spring possible' product for those in colder climates. I like it!

I have been applying coatings for approximately 4years and CSL was easy to apply, extreme slickness and gloss. Great coating!

Awesome coating, was easy to apply but wasn't my first time coating. The gloss level was amazing! Took about 3 1/2 hours on a Mazda 3 coat.

I was very interested in coatings and after looking into the alternatives, I chose Crystal Serum Light. The product is easy to apply and the results are fantastic. Great shine and feel to the touch. I'm glad with my purchase.

I used C1 And EVO before they came out with Crystal Light Serum, After using CLS I wont use anything else. The finish is now so shinny, it actually looks wet. And living in Florida it holds up very well. The best feature is that its a one step process, but only if paint is in good shape.

Gtechniq Crystal Serum Light is by far the best consumer available coating on the market. Im a Gtechniq accredited detailer. Ive been using C1 and Exo for years, as well as Cryastal Serum pro. Serum Light is not much less of a coating than the pro product, and its very easy to use so long as you follow the instructions. Keep 2 towels handy. I chose to use new, high quality 70/30 blend microfibers for the job. Apply in a 2x2 ft area, go side to side than up and down to ensure an even spread, then remove immediately. This coating is not like quartz coatings where you need to let them flash. As far as performance goes, its very glossy, very slick. Offers just as god swirl resistance as anything else, and superior chemical resistance to everything ive tested. All in all, CSL is an amazing product for the consumer and professional alike. It can be topped with exo for added hydrophobic behavior but csl by itself is much slicker.

Really adds a nice deep gloss, I could see the areas on my car that I hadn't applied it to. I did find the application somewhat difficult, I have smears in certain areas. But overall I would definitely buy this again

I've been using C1 & Exo for about (3) years now & love the combination of the two. Yes its time consuming to apply, but the results after is amazing. Was a little hesitant about the CS Light & was up front with customer that it was first time using it. Even after explaining to her that i had C1 & Exo & the difference between the two; she wonted CS Light. Well after the prep work i begin to apply.

It went on easy enough, wiping with two micro fiber towels wasn't a problem. Over all everything went great. The only issue i have is that it dries up to quickly. An yes i worked a 2x2 section at a time, in a garage & the temperature out side was 64 degrees & 69 inside.
So i started reducing my coverage area to 18"; then down to 12". This seems to be the magic numbers when applying,12 to 18". Time will tell how well it holds up & if it does then CS Light is going to be the go to coating for me.

Okay, I've done two more cars with the C1/EXO combo and have waited 1, 6 and 12 hours to apply the EXO. Directions say 1-12hrs. CS light by itself I highly recommend the slickness and gloss it provides is absolutely amazing. I would NOT put EXO on top of this if it were my car, but the customers have insisted they want it. The EXO is fantastic of top of C1, but when putting it over CS light, I feel like I'm ruining the finish.

Just applied this to a friends car yesterday and like C1 & EXO, application was easy, only time consuming. Working in small sections, I would lay down the CS light and then immediately go over very lightly with a MF towel to help spread it around. It started out with almost a slight tack to it, but as I continued to massage it into the paint, it would clear up and get really slick. So much so, I almost didn't think it was worth it to top with the EXO, but did anyway. Can't comment on the durability, but I've had C1/EXO on my personal car and it's been going strong for 8 months and this is supposed to be better.
