Going to detail my dad's infiniti i30 - 200k miles on it and the paint is in okay shape, but it has light surface rust spots (really really really tiny pin-***** marks, nothing huge and barely noticeable) I'd like to try to remove. Can I wetsand them out with some ????? grit paper then apply the paint/clearcoat I got from the dealer, and re-polish/wax the area? If so, what grit would I use (again, by hand, not a sander, because these are just tiny pin-***** marks so no need to sand the whole area)
