Wait the 2-3 days. It definetly is less gummy.
Was this Enviro Tex...?

Too level 1000 will not do it. Too fine.
But you can work your way backwards to find out what paper to start
with.... You can start with 400 and find out if it is cutting fast
enough, if not move down to 320.... But I do urge you to wait the 2-3
days. So you don't fill your sandpaper with globs of soft epoxy.
Softer sands faster, but not evenly.

If you were not looking for a fine finish, I would say go ahead.
You would topcoat it later. But you are looking for a fine finish aren't
you? A little patience while it hardens fully. It will powder off nicer...

Ok cool. Then that is what I'll do. It sucked though because the

Rubbing my hand on it, I hit a terribly sticky spot. Uncured epoxy :/

Are you 100% sure that it was epoxy? I ask because casting resin is usually
polyester. People tend to call any two part resin "epoxy" but that is
something totally different from polyester.

Polyester resin needs two things to harden: the first is the catalyst; if
you mixed the catalyst& resin even cursorily I would not think your lack of
cure was due to lack of catalyst. The second thing it needs is lack of
air...polyester doesn't cure completely if it is exposed to air. The reason
for that is so that multiple layups can be made. For exposed surfaces, one
uses a "finishing resin" which has a bit of wax dissolved in it...the wax
keeps away the air and the resin cures hard. I've had occasions when
finishing resin stays tacky in spots, no idea why, one would think that the
wax layer would be even. Cure is another coat or dust with something to
block of air.

OTOH, maybe it *was* epoxy. How long did it take to cure hard? Hours =
epoxy, minutes = polyester.

It is definitely a two part epoxy resin. Made specifically for bar tops. It takes 8 hours to harden and 12-14 to fully cure. It should then be left alone for 2-3 days to completely harden. I poured a layer over the sticky parts because in the instruction manual for the resin, it said to do so if that happens.

The new layer is beginning to harden and is completely tack free!! It is slightly uneven due to the new layer that was poured on, but I will sand that out most likely tomorrow afternoon.

Some say 200 grit. Others say not to. Should I just start an use the 1000 and work my way up to 2000? Not quite sure how to do this properly to maintain that glass like look.
