I am new to the whole detailing. I have a Flex xc and Menzerna polishes. I recently removed the swirl marks from my truck, which I was pleased with, and my father's truck without clear coat. On my truck without clear I tried small areas with different pad/polish combination. I found that my orange/Menz Power Finish had the same results as the yellow/PF. My question is how do you know when you have the perfect combination. How do you tell that you have went too far? I know if you see scratching it is too aggressive but is that what needs to be done to remove oxidation? I always wonder can it be a little better? I know each situation is different but I have not been able to find this answer while searching. If anyone can provide a link or their comments it would be appreciated.
