Yes, apply with a PC for better results. Obviously it isn't that aggressive, but its a great final step before wax. You may want to try 3M PI III MG - very versatile product that removes swirls but also leaves a great finish - I go right to wax after it. Many others will agree.
3M Polishes are great, once worked in and when they start to dry and dust just a bit, they're ready to wipe off - and they wipe off very easy.
