Hi Mike, I only have one car and when I used it I had a 2009 Cadillac CTS black raven (non metallic paint).
Not sure what to tell you about the results you're getting from Wolfgang Deep Gloss Paint Sealant. In my experience on black and any color, it always produces a very slick, deep shine after the proper paint prep.
I realize various factors influence how long Black Label Paint Coating will last (UP TO 3 YEARS), but what criteria would indicate that I need to reapply?
About the only way you can tell that any product is being worn off is tactically, that is with your sense of touch, the paint won't feel as slick as it did after application. And water beading will be diminished.
I'm not a proponent or fan of trying to treat a car with any product and then let the car go for years. Instead I teach and practice preventative maintenance, the same way you change the oil in your car's engine before the oil loses it's lubricating and protecting ability you want to regularly maintain your car's finish.
With all coatings, this means new ways of inspecting, prepping and maintaining both the paint and the coating will need to be created, I don't think we're there yet as an industry for any coating yet outside of the two tests I included above and actually only one test works with some coatings as most don't make the paint feel slick.
I have never applied paint coatings, but I am fairly experienced in detailing. A few of the posts have me a bit worried. It seems simple enough. Are there any tips or suggestions those of you who have used these products would give?
This is where it helps to have a memory that works as it relates to knowing where all the info on this forum is and then sharing it instead of re-typing it.
Tips for using Detailer's Paint Coating
Last question; I have read various posts about using the paint coating along with a sealant and even a carnauba wax. There seems to be disagreement on this so I guess it is a matter of preference.
Is that correct?
Yes.
Theoretically, if a coating is lasting, protecting and making the paint look good there's no reason to apply anything over it.
The "issue" is... a LOT of "Car Enthusiasts" LIKE to do things to their paint all the time. It's really as simple as that and that means personal preference as it relates to "doing something" to the paint even AFTER it's been coated.
