Hi, I picked up some of the zaino zpc for my car that had swirl marks from a buffer. It seemed to work well. I applied it by hand and had good results. The zaino site says you can use an orbital or buffer. I was just curious to know if anyone has tried this product and if you did it by hand or with a buffer. If so, what size buffer and what speed. I was also curious to see what brand of towel people are using. I read canon or Fieldcrest on the website, but I do believe they are out of business. I was looking at picking up some supima towels from sears, but Im not sure if those are the best out there. I have purchased a set from zaino, but I would prefer to save the $25 and get something locally.
