I have used Jet Seal before and it is more of a sealant than a coating or at least by old-school definitions. As I said earlier, the lines have gotten kind of blurry between sealants and coatings. If there are 10 oz. or more in a bottle it's designed to be used more often than the old 1 oz. bottles coatings came in. These little bottles usually came at a high price, often hundreds of dollars, with a sponge or dense micro-fiber cloth. They were applied a few drops at a time. They can be quite finicky and if you aren't paying attention you can end up with high spots. Temperature and humidity can come into play at the time of application.
I have moderated a Detailing Forum for over 20 years. You can imagine quite a few products have come my way to try. At the end of the day, things have changed a great deal from when coatings first hit the scene.
If you go with a true coating, proper surface prep (claying, clay cloths or mitts, decontamination, polishing, etc.) is key to getting the most out of the coating. Remember once the coatings go on, anything that was showing before they went down (spider webbing, micro-marring, embedded contaminants, buffable scuffs) is going to be there for a long time. Coatings do virtually nothing to hide blemishes, they do not fill like waxes and sealants. So make sure that you or whoever is preparing the surface knows what they are doing and has the equipment to do it right.
Ease of use, just makes sealants a no-brainer for me. Others want to be able to put a coating on their vehicle and not look at it again for years. Decide which type of user you are and go from there.
