Adding some more to Guz's excellent information -
You can "maintain" Mohs with a variety of products depending on what you prefer doing -
- Can Coat can be used, but I think if you are using such a high-quality coating in the form of Mohs, I don't think I would bother.
- Using a "ceramic" drying aid after each wash will keep the coating in great condition. Staying with Gyeon, that would be their Q2M Ceramic Quick Detailer. NV Boost v2 or even Meguiar's Hybrid Ceramic Detailer would also be great options.
- You could also apply Gyeon Wet Coat every 3 or 4 months. This provides a decent top-up with minimal effort.
- You could also add a layer of Gyeon Cure or Carpro Reload 2.0 every 6 months.
You wouldn't need to do all of those. If you are using an appropriate drying aid, then that should be sufficient.
The applicator Gyeon includes with Mohs is a smaller version of their Q2M Coating Applicator. I threw mine in the bin after use, so I would be ordering some additional applicators, I like the TRC Pearl Applicator.
For towels, you would have at least 4, which would give you two sets of leveling and final wipe towels. I swap them half way for thoroughness. Towel choice needs to be a careful compromise between quality, low pile and cost. I throw coating towels into the rag pile after use to be ultra safe, as such you don't want to be spending $10 for each towel. But then, you don't want a towel to be so cheap that it undoes the work you put into the paint. I use TRC Edgeless 300's, but TRC Edgeless 245 are another balanced option. Otherwise, look at TRC Edgeless Pearl.
Ask as many questions as you like, the feedback I got from this forum is what gave me the confidence to tackle coatings.
