After my novel above, I realized that I probably spent more time talking about the WHY rather than the WHAT...and maybe that's more of your question.
So, in terms of WHAT a "Ceramic" coating is, let me clarify exactly WHAT it is...or what it SHOULD be...
Having a ceramic coating involves 2 very simple steps/processes:
1. "
Paint Correction". This removes all the previous waxes, polishes out all the micro-scratches and imperfections, and provides a clean and shiny base for the ceramic coating.
2. "
Ceramic Coating". Here's where the differences lie and will start the war at the Thanksgiving table! Bottom line, without any argument or defense, all "ceramic coating" products are NOT the same!!!! Currently, products such as SystemX (used by Hayes) and Sensha (use by BMCC) are "world-class" ceramic products with long standing research and guarantees.
A good ceramic coating will be rock hard and even rated on the Rockwell scale up to 9H hardness. But, fact is, it must be a pure ceramic product from a good company and not just a company that wants to jump on the hype and "add" a touch of ceramic to there "spray-on" bottle product. This won't work! It won't last! And, all of that prep work in step 1 will have gone to waste.
Keep in mind, TRUE CERAMIC is a liquid that is VERY VERY VOLATILE in that it "COOKS OFF" so fast that the technician has to know what they're doing and work methodically in small sections! This product needs to cure for 24-48 hours INDOORS so as to avoid any moisture of contamination. So, when you've got yourself a fancy "spray bottle" claiming to magically and easily apply "ceramic", run away...it's not going to work.
Yes, after a good correction, and application of your favorite wax, your coach will look good, but only for a while. And, I can guarantee you it won't look anywhere near as good as a coach that's been coated with the world-class ceramic product.
I'm not being critical, I'm being honest because I've done them all; wax, spray, protect-all, glaze, SiO2 BeadMaster, etc. etc. etc. I've wasted time and money...they don't last and don't compare to ceramic...period.
One note, from Matt at BMCC, is he always likes to inform people that their ceramic is paint PROTECTION, not paint restoration. So, once your paint is shot and beyond repair, no ceramic coating is going to bring it back to life.
