Here's what that means,
If you like a product, that usually means you like the experience of using it which includes application, that is you like how the product applies. It also tends to mean you like how the product removes, that is you like how the product wipes-off. It can also mean you like how fast or slow it dries or the fact that it doesn't have to dry at all and you can wipe it off immediately.
And usually and most important, it means you like how it makes the paint on your car look and that's a huge part of the big picture of owning and enjoying your car, truck or s.u.v. or special interest car.
You can't really know which product you like best until you've used a variety of products so finding something you like and using it often means you have to do some research and at some point make some purchases and then go out into your garage and do some testing to gain real world knowledge and experience.
At some point you will find a product you like and if you use it often then your car's paint will always look good because it's only when you neglect your car's paint that it goes downhill.
Just the simple act of applying and working-in and over the paint a smooth, creamy product, (that is formulated to make paint look good), has a polishing-effect and if done on a regular basis will preserve and maintain a clear, glossy finish and isn't that the primary goal of those that consider them serious car enthusiasts?
How often you have to repeat this process to maintain your car's finish to a quality level you expect for your car's appearance depends upon how the car is used and where it's parked when not in use.
A daily driver that is parked outside most of the time, either at work or at home, will need to be maintained more regularly than a Garage Queen that is only driven on sunny days. So adjust your car maintenance schedule to fit your lifestyle and the way you use your car.
