Hard to tell without any pics or eyes on the cap.
If you were in the oxidized area it will just come off the oxidation color. Gelcoat is quite hard so it may take a very course compound to get any color to show.
Some actual pictures of the cap, close ups of the oxidation, colored area and where you used rubbing compound.
Also maybe a pic of the compound, not all of them are as effective as others.
