I recently purchased some 1:43 scale vehicles. A few had scratches or rub marks on the roofs -- likely from where the roof rubbed against the packaging. I have a Dremel tool and two buffing tips -- one flat and one pointed, along with some rouge. I've never used any of these items before (although I have used jeweler's rouge on silver years' ago).
Because there's no hidden place I can first test these Dremel accessories out on, perhaps one of you can offer some advice? I don't want to make the scratches worse or end up with an even worse dull spot while the rest of the vehicle remains shiny.
My hope was that the polishers could remove the dulled/scratched paint and reveal a shiny surface below. That assumes that the paint is thick enough for that to work, and on one vehicle it probably isn't.
So, should I use the flat polisher/buffer to avoid creating a divot? (Actually, once it's impaled on the metal shaft, only the edges will be safe to use.) Or, will the pointed tip provide greater precision and control for a light touch?
Would you recommend using the rouge or just the buffer? I will use the low speed setting, of course.
Thoughts? Experience? Do's/don'ts? War stories? Attached are photos showing one of the vehicles and my Dremel tips.
I'm even wondering whether a simple application of some good old Turtle Wax would be best to just fill in the scratches and keep the surrounding paint shining without the risk of using the polishing accessories. Maybe that's the best place to start? Do no harm and all that. 
Thanks in advance,
