About to start my first full car(s) correction. My wife and I just bought two CPO BMWs and are looking to correct them back to new finish. I have been a Zaino user forever and see there are many other options on the market now. We had always bought new and it was easy to maintain the finish with Zaino, now we need to correct them because the Zaino only seems to bring out the swirls. I have a PC 7424XP and ZP-C. I have never used the stuff, but in my fingers it feels too thin to correct anything. I really would like to make this a one step process since I have two cars to do, but is the Zaino going to give me enough correction or should I just go ahead and buy something with more cut now. The white really makes me nervous with getting a good finish, it is already difficult to see the swirls. Here is a pic of the worst of the spots on my car. Pic uploader is down, I try to add again in a few.
