It all depends on how deep the scrathes are. If you look at the scratches and you see the grey primer underneath it or if you run your finger nail over the scratch and your figner nail gets caught on it pretty good then it has to be repaired by paint. I would personally try some scratch-x by mcguiars available at your everyday carparts store, ie napa, autozone, o'reillys and you can do that by yourself. It doesn't cost that much and its something you can try before you spend 200 dollars on painting it
