I have an older Olympos PPO-EP02 flat port that has some marks on the glass (water spots on the outside mainly). I suppose to preserve what is left of the coating I should just ignore it, but does anyone have any success stories (maybe lenspen or similar) with cleaning up those kind of marks?

It might just be calcium carbonate. You can our some vinegar on the glass and let it sit for some time. Then wipe off and dry. If the marks are reduced repeat till gone.
I had good luck using Novus #2 (mild abrasive) with a soft cloth to remove stubborn water spots from my flat port. Just rub slow and steady with light pressure. Follow up with some soap and water.
I bought a really great electric blower and now use it to dry off my housing and ports after rinsing at the end of the day. I think this helps a lot of avoid additional spotting. This thing is powerful and works really well.

OP
Is it better than the compressed air guns (typically powered by a scuba tanks) often found at dive resorts and on liveaboards?

CLR cleaner (calcium, lime, rust) works well at getting salt spots dissolved. Safe on glass and any hard plastics like plexi. Then you can clean it up with water and a soft cloth after that.
It's just as effective, and a hell of a lot more convenient. Surprisingly powerful. Small, rechargeable, adjustable power level, long battery life, and does not require a 45-pound tank that runs out of air all the time. I dive locally all the time, so I get a lot of use out of it. I've taken it on a few flights as well, no issues. The one short coming is that it does not have an "off" switch, just a trigger than can bumped in a bag. My solution to that was a 3d printed "trigger lock" that covers and protects it from being accidentally activated when being transported.

Nice toy, I might need to check that out. I have one of the rocket squeeze blower things every photographer has in their bag, but that looks to have a lot more utility minus the arm workout.

The novus stuff is great on plexi, but won't really do anything on glass aside from acting as a cleaner. Glass is way too hard, and if you do somehow manage to get actual scratches in glass, novus isn't abrasive enough to grind away material from glass.
