I did this ages ago with my random orbital polisher (similar to a PC 7424), a light cutting pad and Poorboy's SSR2.5 swirl remover. That was about 10 mins work and I did one pass.




This next shot was after using Turtlewax on a polisher similar to yours and I polished for about 20 mins.




I'm not bagging your polishing efforts but if you want to get a 'perfect' finish then you really need to use decent polish and polisher.
