Dry Lock

Had a little bit of water coming in through a concrete block foundation in one location.

Installed french drain outside plus rain gutters.

Leaked stopped inside.

In heavy rain the interior wall gets damp only

if I dry lock this small area will that be a good idea.

Or should I leave it alone?

If it only gets damp it won't do any harm. As long as there is no pressure behind the dampness.

Were you thinking inside or outside?

If inside it will just trap the water, you really want to repair the outside with a good waterproof membrane to keep it out of the block!

Painting your basement wall with Dry Lock won't hurt. If the wall just gets damp it should do OK for at least several years but I have not seen it hold up long term when water is present.

IMO drylok is more of an added insurance than an actual fix. It will stop minor leaks but then were does that water go? Sometimes it will just back up until there is enough pressure for it to find an exit. It's always best to stop the water on the exterior side! If all you have is dampness it should work ok.
