You should have left that spot to cure. It probably didn't have enough
hardner. But it might have cured in a couple of days with just a little
hardner.

Anyway. I used to work with epoxy regularly. Yes it sands well. Just
wait for it to fully cure and harden in a couple of days. Yes I know
most cure fully in 24 hours. But you want them to harden, and that takes
a while. Then it won't clog your paper as much.

You can use a good quality paper to quickly take it down.
Using 120grit... progressing to 320 or 400. I used to use freecut gold
(3m) for that. Any good paper will do it.

After that start using wet/dry paper and progress. Water work. I used
sikkens m600 instead when I had to sand a lot off. It cuts cleaner with
less loading of the paper. Just where nitrile gloves. Then I would go to
1200 paper... when done let it sit for a day... then buff.

If you have access to an automotive paint supplier... see if they have
liquid ebony for the most beautiful final polishing. It takes out any
swirl marks from buffing.

later, there are 2 areas where the epoxy remained uncured, which
means the batch was not mixed properly. I scraped off as much as
possible and just poured a new layer over it.

Problem is, the coating is now uneven due to laying another coat only
on the sticky parts. Once it dries, can I sand it even and
progressively get higher until I reach 1000 grit. Then buff and
polish it to glass again? I just don't want to lose the clarity of
the product.

Yes. You may want to go higher than 1000 grit though. Common automotive
buffing compounds will generally buff out 1500 grit scratches. You can buff
out 1000 grit, but it takes a lot more effort. You might want to go up to
2000 grit before buffing - it'll just make life easier for you.

Ok cool. Then that is what I'll do. It sucked though because the finish looked perfect. Then when it was dry it felt like glass. Rubbing my hand on it, I hit a terribly sticky spot. Uncured epoxy :/
