Our son-in-law and daughter scraped the popcorn off our ceilings and one of
them (I won't say which one :-) got carried away and scraped too much,
gouging the finish in some areas.

From the other answers I've read about popcorn ceilings, it sounds like my
best bet is to get some watered down drywall mud and put it on those areas
with a sponge. Any other ideas?

You probably need to skimcoat the entire ceiling. This is an art by
itself, but the average handy person can learn it. There's a little

Google will give other results.

Skimcoat, sand, texture, prime, paint. We just did this in our living
room after removing popcorn ceiling. Looks great.
