Thanks!
For ceramic coating, which one do you use and what advise do you give to clients re curing and water exposure? I have a client who was interested pulled back after hearing that cquk 3.0 would need 48 hrs cure time without water contact.

Right now I am using McKee's 37 exclusivelly. I am planning on adding Gtechniq CSL eventually but that product is a little more tricky because of the water exposure issue you mentionned.
So, with McKee's, I am mobile and do most of the work outside. Sometimes people have garages or are parked in underground garages but these are uncommon for me. What I do after applying the coating is I apply CarPro Reload on top to protect the coating during the cure period. McKee's doesn't mention what the cure time is but for most coating it's a week. The first 24 hours are the critical part where you don't want water on it, afterwards it should not be an issue. So for the first 24 hours, and during the rest of the week, the sealant will protect the coating from getting wet.
What I tell clients is this: Do not wash the car for at least 7 days after application. If they ask about water exposure I explain about the sealant.
I also send them an email with a reminder of things to avoid doing (automatic car washes and the like) and a video I made explaining how to maintain the car.
As a side note, I think CQuartz is a very bad choice for a detailer to use. As far as I know, you have to apply 2 coats. So that is 1 hour of extra work for you, plus the time you have to wait between coats. Also the product is really expensive for a 2 year coating. McKee's 37 is 45$ for a bottle that will allow you to coat about 5 cars, Cquartz is what? 70$? And you can only do 1 car with it. I tested EXO and it was the same issues, I did 1 car and had only about a quarter of the bottle left. So I will not be offering EXO. Also the durability of EXO and CQuartz are less than McKee's, so I see no reason to offer them.
CSL is a product that Gtechniq warranties of you are an authorized installer, so I have confidence the product is good. Also it's a 1 coat product and it's very easy to apply, just like McKee's. The only reason I am not offering it is I fear it might confuse clients and make them hesitate. Right now my close rate on coating is very high. I would say I close 80% of the people who contact me. I don't want to reduce that. You know the saying, don't change a winning formula.
