remember it's a clear over colour paint job! if the colour is still there you could try a clear filler like those clear coat pens or a small brushed bottle then once dry plenty of polishing.
If the colour is gone you will need the base colour and the clear.
If you dont have experience doing this and the scratches are deep,have a pro do it! Otherwise it will look terrible and you will need a pro anyways. A pro can wet sand and polish and bring it back to new but without seeing what you are dealing with it's all speculation!
If you have never done wet sanding,dont attempt it without lots of practice!
YMMV!
