I’ve been wondering about this issue too. Wonder if it’s the business tactic to lead us to spend more or if the PPS really require topping up of the coating.
If claim to be good a ceramic pro coating should last up to 3 years i believe?

Below is Non- ceramic pro related which briefly explains” if it’s the business tactic to lead us to spend more"
Varied brands have different ways of taking care, running costs. Generally, for inorganic coatings, they will not be "washed" off with shampoo and the way to maintain is to keep the surface clean with proper washing with shampoo. Let's take our old theory of cleaning a non-stick pan. After frying an egg with a non-stick pan with minimal oil, pan still have some grease remains after rinsing with water. A bit of shampoo will do the trick, right? Choice of equipment - shampoo with rough wool VS soft sponge, which will damage the non-stick pan faster? When shampoo with soft sponge gently or with elbow grease. Which will cause more damage? Our environment has oil base contaminants which minerals will settle on and start their own cycle of reaction and start attacking the coating. Different brands require different type of after care. If care is taken as suggested by your applicator, you should not be spending for more than you should provide brand has good reputation, applicator's environment/facilities, procedures for application, workmanship, cleanness and perfection of surface will have an impact on durability and end result.
Just for sharing,
Couple of weeks back, when we are doing our weekly checks, we pass by a detailing centre that caught our attention. Patches of greyish substances can be seen all over the place; most likely they are mould. 1 gentleman is applying the coating in an uncontrolled environment with an applicator pad and 3 guys were wiping down the coating on the door so hard that the poor car is shaking. Several reasons for the extra effort. One thing for sure we know, before the product can protect the paint, their guys had induced marring and micro scratches to the paintwork. Has the product been cleaned out by them?
Of cos, there are some bad hats in the industry to be careful of who are easy to identify from company's inconsistent brands used, high company owners turn overs. Unrealistic number of "Likes" and "reviews" on social media etc.
It takes 2 hands clap. Quality of products, applicator, owner’s care, plays a role on durability and possible running cost. Hope this enlightens
