When you say the scratches aren't deep, how deep are we talking? The standard finger nail test should let you know what the script is with them. If you can catch the scratch with your fingernail its a respray. Otherwise, as has been suggested a polish with good filling ability such as AG SRP, AutoFinesse Tripple, Prima Amigo would help mask them, but again as mentioned already you would have to repeat this process. Only way to permanently remove them is either with DA or rotary and compound. Hope this helps.
