You really need (IMO) to get a full set of micromesh, rather than just one sheet, as the benefit is being able to go up the grits.

I buy a set like this. https://www.amazon.co.uk/Micro-Mesh-...type=ss&sr=1-3

They last quite a long time, so I tend to buy a new set every other year with my usage. They are the final polishing stages, so your normal sandpapers do all the heavy lifting and wear.
