Nice. I know they came with new Audi cars, was about to step on my pride and ask for one in a dealership.
I'm not good with any kind of pencil, but there is no way it can get worse than white scratches on black paint.
Trust me - you can. Because when you add paint to the scratch, you will be unable to fill it up perfectly to level, but rather you'll add more paint than necessary. This will actually widen and raise the area that's now not perfectly level/flush with the rest of the paint - and what's even worse, it will now also drop a shadow, which will make the area that's not exactly the same color/level as the rest of the panel, even wider. So, where you had a small scratch, you will now have a wider line that just draws the eye, because it will stand out and not be exactly like the rest.
A person who is experienced in detailing can correct that by wetsanding the surface, which is essentially the process or leveling it, by removing some of the paint/clearcoat, that was put on. It's a very delicate process, and afterwards you even have to compound and polish the paint to remove the sanding scratches and blend it in with the rest of the panel. But even then, if your car wasn't brand new, the touched up area will still be visible to the trained eye, if you look very closely - because it will just not be exactly the same color as the rest. That's because the paint on the car has been bleached through the years by the UV radiation, whereas the touch up paint is exactly the same color as the car was originally.
Anyway, unless you're familiar with the process above, you will most likely only make things worse.
And I have a few light scratches that need to go..
If you have light scratches, that don't reach down into the base coat or to the primer, then those can be removed completely by machine polishing. If you have deeper scratches (that catch your fingernail as you run it across them in a perpendicular way), then you will not be able to remove them completely - but even then you can mostly diminish them and take out most of the "white" part of them (so, again, they will only be visible to the trained eye, and only on very close inspection) by machine polishing. However, even this process requires someone experienced, because a) you don't have a chance without proper machine, pad and compound, etc. b) you can easily make things worse by removing too much of the paint and burning through the clear coat.
Anyway, feel free to try the touch up paint thing, but expect only making things worse, and having to hire a professional detailer or going to the body shop afterwards to get actually acceptable results.
