[Closed] Fox 36 float rc2 service

Hi. I Serviced my forks the other day as in oil change and a good clean as they feel slightly rough. But they still do LBS have suggested probably changing seals and servicing air cartridge. Now I've not really looked into this as forks still in bike but I'd like to give it a try myself not just for saving money but experience. I consider myself quite competent but is there any reason not to as in special tools or springs flying everywhere. Just thought worth checking before stripping down and buyin seals. Also is there much difference in genuine fox seals and the tf tuned ones.
Cheers
