lol ok fair do. if your adventerous and have the time / space why not do it properly. All you need is Rhino wet&dry sanding paper get 250grit a 800grit and 1500grit, metal primer, aerosol made up to your colour. Some halfords mix up paint to the correct paint code mine is 176/a Rosso Passionale / Exotica Red. You can get it on a silver sticker that should be under your bonnet.
1. Sand out scratches with rough and then fine paper upto 1500 grit until smooth. Rhino Wet&Dry paper rules.
2. Mask off area
3. Prime the area with a metal paint primer remembering not to go upto the masking tape or paint will build up 2mm thinker than your normal paint
.
4. Use fine layers of primer and once each layer is dry use the rhino paper to smooth the area thats painted.
5. Do the same with the black aerosol keeping it fine layers and remembering to sand the area in between each coat.
6. Once dry (allow 3 hours) use a laquer, again keep it really fine this time don't use sand paper in between coats.
That should get you a nice finish. I had to do this on my Brand new GP front bumper due to similar scratches as yours but mine were a little deeper due to it being plastic. I just couldn't bare to part with £250+ to get it done in a spray shop.
