Not meaning to be a smart ***, but I'm assuming you are talking about wet sanding and using a soft block? Anyway, the step from 1000 to 2500 is too big, the 2500 won't take out the scatches the 2500 puts in... Might want to add some 1500 then some 2000 between the two grits you have now... As for the swirls, either excess material or material residue.... Make sure all the rubbing compound is off the surface before you use the glaze... After the glaze you could try some polishing compound, then if necessary a swirl eliminator, then some hand glaze... If it was cheap and easy, everybody would be doing it.

I'me sure the pro painters will be along with some other reccomendations to resolve the issue....
