I've been using this product for quite a while now. It is my "money maker/time saver".
I typically use it like a "cleaner wax", but this past weekend I did something different.
It was a car that I had done work on in 2015. It was getting a "lease return package". Since it had been a while since I worked on the car, it had some damage. Thus, I thought I'd approach M66 like it was a Polish.
I started with four drops on a black finishing pad, spread the product around the work section, and did four moderately slow section passes. I couldn't believe how much the paint was able to be "cleaned up".
I reloaded the pad with two or three drops, and wiped clean with a microfiber between every section pass. Since he was turning the car in, I didn't bother letting the wax dry before wiping off, and it still had a clear, slick finish.
Just wanted to mention how great this product is.
