Look anything like this?

Gel-coats historically love compounds with wool pads on rotary buffers. This combo will chew threw any oxidation and leave the surface very glossy and shiny. There will be swirls or hash marks from the abrasives and the individual fibers that make up a wool pad but nevertheless, the surface will be clear and shiny.
If this combo isn't creating a high shine or high gloss finish to these dull spots that's a red flag.

I've never used any of the Presta products. I've known about them for years just never used them. In a couple weeks I'll be doing some work at a shop that used to use them and I'll see if I can get a bottle or two just to test out.
Besides that, kind of off the cuff, do you know 100% for sure the house and bridge don't have a painted surface like Awlgrip?
It just doesn't make sense that the hull will polish out but the topside won't unless there's something very different in the surface/surface coating.
It is possible that a higher quality, or at least a different abrasive technology could make a difference in the buffing results, but the only way to find out would be to do some testing.
Sometimes, a real simple approach can work like taking a light cutting cleaner wax with a wool "finishing" or "polishing" pad, (not an aggressive cutting pad), and re-buff the area at a medium speed with your rotary buffer.
That's what I would try next...
