What kind of products do I want to use? I'd like to be able to do it by hand as I have no mechanical buffer of any kind. I have a small white paint rub on my Santorin blue exterior and I've noticed some very very light 'scratches'. They look like they're just rub marks in the top as they aren't white (like an actual scratch I had the dealer buff out), but they are noticeable.

I use Griots products myself and that is what I would use.
