I've had my Audi for a very long time at this point and "technically" plan to move onto another model in a couple more years. It's overall in very nice presentable condition with only minor spots of body damage (a shallow swipe on 2 quarter panels, some "dog bites" to the rear bumper cover). The paint is still in great condition despite having detailed it only a few times during ownership.
However, I have recently taken notice of some very tiny rust spots on the hood, towards the front end. Maybe a total of 10, with only 2~3 being the largest of about 2mm in width. It doesn't seem like enough to warrant a paint job. But I want to stop the rust from spreading.
Has anyone here done this as a DIY, and if so, do you have any recommendations on how to go about doing it? I expect that something along the lines of scraping off the visible rust, priming, then applying touch-up, followed by polishing to flatten any raised surface. But rather than just winging it, I'd prefer to follow a procedure someone else has found to work well. Thanks.
