Hey Bill,
Touch-up paint can be done well. Can you see the damage from the sides, or only from the top? I personally would not lose sleep over the scratches...HOWEVER: if they are going to do it for free I would have it done. If you are like me it would bother you every time you see the scratch, and you will say to yourself "why did i not get those things fixed?"
Also they bake the paint to make it dry quicker and look better!
I hope this helps!
