From experience using coatings and other items, I will try to help the OP and several other posts that mentioned sealants vs waxes etc..
1. OP--- You possibly might have gotten the straight line scratches while doing the Coating cleanser. I can say I tried it myself and ran into a ton of issues on black paint. Machine apply with black pad and immediately taken off still created faint marks. This is likely where you got them from, or when you are drying the vehicle with MF. Wash Mitts will sometimes do it too pending what type on dark cars.
2. Topping coatings--- They can be topped no problem. But remember what ever the LAST product you put on, that is the type of water effect you will get. So if you top the coating with a spray wax, you will get a wax effect on the paint not the coating. Same goes for a sealant. If you blow dry the car with the Blaster, you can see the difference clearly. Coatings-- the water will fly off and leave it dry, a wax or sealant topping it will cling in tiny droplets and it takes three times as long to get the water totally off. Thus, PBM creating the Black Label products to act like a spray detail, spray wax, or booster. They work with the coating and have similar properties as the coatings. Waxes and Sealants do not cross link so therefore they are added protection, just don't work with the products.
Give you a great example:
Car 1-- You detail and use a brand new sealant on it trying it out.
Car 2-- Same thing, your wanting to choose which one to use
Three months later the customer brings in both vehicles for a quick wash and go. Great time to check them out. After you clean the paint and go to rinse you notice Car 1 is beading and pushing water off like crazy still. Car 2 is beading ok, but not really shedding the water as much. Logic says that the sealant used on car 1 would be the better choice to use for where you live because it appears to have lasted longer. Most people would choose this and then discredit the other product to whomever they know uses it, and not recommend it to any customers again.
What you didn't know, was the customer for Car 1 just two days before and right before the rain heavily used a Spray wax he picked up from the store and didn't tell you he used it. Therefore you were seeing the effects of the Spray wax, not the superior sealant. Car 2 sealant was actually better, but you didn't see it.
This just shows how each product will overlap what the one below it does, so just be careful of the end result you want, and don't change it just to use a extra product. Make sure the products work with each other as they were manufactured to do. Ie.... Black label with Black Label are meant to work in tandem, not against.
Hope all this helps explain a few things. Coatings are a great product and help ease maintenance. Black label seems to have gotten the price per vehicle down, so now more customers or personal vehicles can be done with it for the longer protection qualities and gloss, without having to spend 400-500 for others. My personal vehicle has the other though. Worth it for me
