OK, first off: STOP THAT.
What you've done is etch away to cement and exposed the sand and
aggregate. Over time this will wear smooth again, but you may not want to
wait.

Rent a concrete floor grinder and you should be able to take off the high
spots: then relax and stop typing to keep the concrete pristine white: let
it gain character and -be- the zero maintenance surface it's supposed to
be.
Overlays and coatings are a crummy solution to the problem IMHO.
