CQUK difficultlies

[parshisa]

I’ve been installing CQUK on my civic for the first time and I can’t say it was a smooth sailing. Ambient temp in the garage was around 65 with humidity in low 40s. The problem is that coating would become sticky the very second it got on the paint. I wouldn’t even be able to level it out with applicator pad before it becomes sticky and grabby. And it wouldn’t even flash yet (visually it would start flashing with 3-3.5min). I was able to remove with mf towel but it wasn’t anywhere close to what I saw in the videos. I ended up leaving it on the paint for 2-3 minutes before removing it and used short pile mf towel using short strokes with very little pressure (otherwise it would just grab and hold me back).

What was I doing wrong? Waited too long and too short? Bad weather conditions? Anything else???

Check the date on the bottle, could be old and/or partially cured.

Typically, I will go through 3 suede applicators to do one vehicle. After 1/3 of the car or so application can get grabby as you have described, which is when I grab a new one.

Final thought is that you may not be using enough product.

Thanks for the feedback. 3 applicators was exactly how many I’ve used. Also the product is pretty fresh, around 3 months old. Opposite to your suggestion I think I used too much of the product - whole car and twice covering the hood and I got left a little over 1/3 of the bottle. Could that be a problem?

Hi,
you did well, CQUK dont need flashing time , you can apply on and wipe off, doing even layer not too thick.
work on small areas, like 50cm2 , almost WOWO , the sticky feel is the reaction of the coat , might be the humidity you had too
so even if you wipe off right after its fine, using short loops mf or the suede mf we supply for wipe off.

Thanks for the feedback. Yesterday I was doing another car and used Essense as a primer and it made a HUGE difference. Coating went on so much smoother and wiping off was much easier. On the other hand, I got a 50ml of regular CQ I’ll be using. How different is it from CQUK? I believe I have to wait for it flash before wiping it off? Any tips you could share?

Just curious, with the seeming problematic application, I assume you used a paint prep (Carpro Eraser) prior to the coating, correct?

The first thought was as your first reply in this thread, that the coating was past its expiration date.
I had noted such occurs, that CQuartz can get a little "sticky" and harder to apply when it gets old.

I used a quite old bottle to coat my 6x12 Cargo Trailer last fall. It was just about 2 years past expiration, but never opened. Coming behind to wipe in a small area as a initial test did prove a streaky smeary mess, so I left well enough alone, just applied with the Foam Block and MF Suede Sheets, and didn't touch it after.

Amazingly, I still got beautiful end results. Although I was not looking to achieve perfection as it is just a trailer, I do know I laid down some very good protection on a 15 year old paint finish.

CQUK is typically all I use. I just had to do a spot buff on a car w/ CQUK this morning... Temps were low 60's and a skim of moisture on the vehicle. I did a rinsless on the area first, corrected the scratch, then used erasure and just as Avi stated, worked the small spot buff area... as soon as it applied, I usually just start removing. No issues. CQUK doesn't like to dwell on the paint for a long time.

Correct, it was bare paint wiped with the eraser after polishing. I’ve used essense as a primer on a different vehicle it was much much better as far as ease of application and removal

I've used both and Cquartz TIO just isn't my cup of tea. It does provide a nice gloss and what not but it just doesn't have the same nice look at Cquartz UK nor the durability of UK.

So, when you say TIO2, do you mean regular CQuartz? I’m getting confused a bit as I don’t see it anywhere on the packaging. I got 50ml of this stuff I was planning to get use on my pilot (although pretty much half of the car is already corrected and coated with CQUK). Do you think they will look different on the same car? How’s my layers of regular CQ would you suggest to apply?

CQuartz UK is supposed to be the same product as regular CQuartz but easier to apply in cold climates. BUT, I have read many times that the UK version is much more durable... I don't know why that is. Maybe CarPro could give you better answers than we can. I have never used CQuartz, when I first started installing Coatings I have read a few people having issues applying it. Since I don't have time for problems I chose an other product and never looked back. But as far as I know, the regular version is very sensitive to application temperature and humidity, that is why they came out with the UK version...

Agree with you on the looks as UK looks better on darker paints. I find TiO2 looks better on light colors like white or silver probably due to the TiO2 in the product along with the SiO2.

TiO2

UK

 

[SWETM]

The difference between cquartz classic and cquartz UK is that classic has tio2 in it with sio2. And cquk has a higher concentration of sio2 and no tio2 and the sio2 has more durability than tio2 which has more reflection capability to it. Cquartz UK was developed for the UK climate which is very moisture and more rain. And a higher concentration of sio2 and no tio2 took care of that. Plus they made it to be able to apply it in lower temperature I think. But the big reason was for the weather climate and sio2 is harder and more resistant to that climate. Which is alot like south of Sweden but we have a lower temps in winter but cquk works great here plus it's very chemical resistant as we use tfr and tar remover alot. For what road salt desolves that is on the roads and bonds strong to the paint. And we need to use much of this stuff to get a safe washing.

Cquartz flash little slower now then CQUK , but not much, you need to feel the surface rather than looking if it flash, once it get tacky feeling , light sticky , start wiping off, at average 20C deg ( 68 F ) is about 1 min .
waiting to flash , dry on surface will be too late and hard to wipe.

We use portion of Tio2 inside the Cquartz, in usa they call it cquartz Tio2 , but its the actual cquartz classic we started doing 7 years ago, the Tio2 give the coat more reflective , a gloss you could say.

I don't know why that is. Maybe CarPro could give you better answers than we can.

CQUK is more chemicals resist vs Cquartz has more deeper gloss .

Thank you, well said, even better than me in Sweden, Canada, Norway and UK CQUK perform very well in the hard winter times.

Thanks everyone for the replies, very much helpful! It’ll be interesting to see if the difference between two will be noticeable - I’ve applied CQUK to 4 panels on my wife’s pilot already, the rest will get regular CQ. I’ll post with with pictures and observations once i’m done (it will be another couple of weeks though, looking forward for the days off lol). Again, thanks y’all
