Most of us know that polishing helps to clean your car's paint but here's an example.
The last time I polished my car was about 1.5 years ago, around February of 2016.
I use my car mainly for mobile details and it is kept outside 24/7 in sunny south FL. Here's my setup with the trailer.

I haven't washed my car every couple of weeks as I should since I'm usually detailing other cars and when I get some spare time I don't usually feel like washing mine. Maybe some can relate
.
Anyway, I recently had some spare time and decided to give my car a good wash and clay.
I noticed that it wasn't as white as it used to be even after washing and claying. It was time for another polish job.
I wish I would have taken some pictures of the roof being polished since you can see a dramatic difference in the area that was polished. The roof was the dirtiest as you could imagine. The white color was restored like new again.
I managed to take some pictures of the hood.
Tape line placed on the hood. The bottom part will be polished.

Tape removed. You may be able to see the difference. Hard to capture and the lighting wasn't ideal. The bottom part, below the line, was polished.

Here's another shot. The part below the lines was polished. The arrow is pointing to the tape line.

Moral of the Story
The hood was coated with CSL and topped with EXO in February of 2016. Since that time I've used other products on the hood such as sealants and waxes, mostly for testing purposes.
Since I didn't wash the car on a regular basis, the hood needed to be polished for some deep cleaning.
Therefore, I don't see the need to use a long lasting coating, such as 3 years and beyond, if the car is kept outside and will not be washed on a weekly or bi-weekly basis since it will need to polished in a year or two.
If the car is kept outside and will be washed weekly or bi-weekly then perhaps it will not need to be polished for a while and then I can see the benefit of a long lasting coating such as 3+ years but proper maintenance is the key.
