It will not harm a quality coating. It would act as a topper which could give you a different effect such as water beading being better or worse than your coating. The only negative, imo, is it "could" clog the coating if used on a very regular basis. A quick APC wash would take car e of that IF it did need it. F4 doesn't last months or even weeks in most cases so that typically isn't a concern.
I rent a big DI tank for 23$ a month and it lasts me over a year before refill/exchange which costs 130. my home water was around 50ppm before the system, so that has helped the tank be more efficient, for me it’s worth renting the system rather than changing resin on my own on a small tank
