I have used nothing but Zaino and love it. I now have a few cars that will need my PC to get some of the swirl marks out before I Zaino. I have heard alot about Menzerna products, the 2 products that I can't decide between is PO85RD or 106FF with a white pad. I don't think the swirl marks are major, so this too products I think would work, I am also open for suggestions if you like other products better, thanks again.
