Your detailer does not know what he is doing. Granted, some paint defects are to bad to remove without a repaint, but water spots? Very unlikely...

Compounds are DESIGNED to remove water spots/marks, among other things. Now... the question of the hour...

He had a machine, what kind of machine? Rotary? DA? Autozone Special?
What product was he using? M105? Some random compound from Wally world?

If he was worried about the clear... he must have had a rotary.

I'm going to need pics of these water marks to help you more.

yeah the risk may outweigh the reward but darn it annoys me. most people wouldnt notice, or care. they can only be seen at an angle, or under florescent lights.
My friend hasn't washed her car since she bought it, so I doubt she cares. I was mostly interested in pitting Jetseal109 vs M-Seal on both the hood and Windshield and prepping the car for a 9+ hour trip, so I didn't do anything to the etching I found.

Honestly, if your car has 25-year old paint, water etching wouldn't bother me all that much. If you want to try wetsanding yourself I would recommend starting with 2000 grit which can be found at an auto parts store. You can cut little circles and ovals and attach them to the end of a piece of dowl so you aren't sanding any more than you need to, but like stated be very careful and recognize the risk that you could sand through the clear. Also, you would have to compound and polish after wetsanding.

yeah it'll level the paint. may also take off too much clear coat too. i wouldn't do it, i just learned to live with it, even though it sucks. my car looks good from 20 foot but up close it aint pretty. ate into it pretty good.

Most water spots and etched-in water spots can be removed by a good detailer. In some cases the spots may have actually etched so deep that wet sanding is required, or they may even be too deep to be safely and fully removed. Your detailer may, or may not, be correct. You said he didn't want to risk going deeper with compound? A good detailer should have a paint thickness gauge. If he didn't check the depth of your clear coat, there is no way to know how to proceed. More than likely, a more aggressive pad/compound combination will remove the spots.

Here is some good info about water etching.
