If the lenses were previously ceramic coated you may have to spend a little more time on them but you can get through it and the finish will be like new.

That's correct. A lot of people cannot wrap their head around using sand paper to make such corrections. The courser sandpaper just speeds the process up by removing imperfections and leveling faster. Otherwise, by the time you work up to 2000 or 3000 grit paper, you are nearly at the point of polishing. You can then finish up with an actual polish, if desired.
If you are going to apply a clear coat though, you shouldn't go any finer than 600 grit typically. If you go any finer, the clear may not adhere adequately and lead to early failure. Otherwise, the clear coat will fill in the 600 grit scratches no problem.
