lots of different factors come into play on how long it will last. How you actually wash the car being one of the most important steps in keeping a swirl free finish.

I did my fathers lexus last spring. Got to see the paint in some light this year and the swirls are horrible. BUT - he parks his car outdoors and isn't afraid to use the snow brush directly on the paint to remove snow. He also lets the monkeys at the lexus dealership wash it for him - they probably use a bucket of sand with water thrown into it for good measure. But heh, he has a son that will spend days fixing it! LOL

My subaru - I did the job 2 years ago, still relatively swirl free but my car is always parked indoors, and I'm happy to say a snow brush did not touch the paint at all the last 2 winters.
