swirls suck I just noticed some on my car this morning
but save some money and buy your own Porter Cable polisher. I got mine from coastal tool for under $120.
Before that I stopped by a fairly reputable detailier and they quoted me at least $100 for a 'rubbing compound' application. Not unreasonable since removing swirls and the prep work before that will take at least two hours. At least..
To prevent swirls from reappearing:
I would suggest washing with optimum no-rinse (added to your regular car wash soap) and start using sea sponges. Remove the nozzle and flood the car so that the water sheets off. Blot dry the remaing puddles with a waffle weave.
THis method reduces rubbing on the paint and the ensuing swirls.
Spray with FK 425 or FK 146 (cleaning version of 425) or a regualr over the counter quick detailer for final drying. Lubricate before drying.
As for your swirls I use Poorboys 2.0 or 2.5
start with the one panel and use the mildest product and see if it removes the swirls. Follow up with your Polish and sealant. I'm using Klasse All in One and
Poorboys EX. Oh yeah and don't forget to clay first.
