Hi Guys
The simple answer is that there is no simple answer :

Gloss paints are designed to be chemically resistant and some are more so than others, Epoxy for example.
Another factor is how well bonded in the first place, also quantity.
Pog which is a mixture of solvents, as is white spirit may soften enough to loosen, remember to use sparingly , if a little doesn, t work , then a lot won't either.
Cheers
