It depends how how deep the scratches are.

On metallic paint - if they're through the lacquer and into (or through) the paint then the only way to get a decent result is for the panels to be repainted.

If the scratches are small in size but deep into the paint then you can disguise/mend them using the DIY paint kits. Basically clean the scratch, fill it with paint, then lacquer over it. The kits contain all you need, and the brushes are like nail varnish applying ones.

However, if the scratches (irrespective of size) are merely into the lacquer (but not through it) then they can be removed fairly easily...

Depending on severity, try using a Firecla product called G3 rubbing compound. It's a bit like T-Cut but stronger - it'll take away light scratches with a bit of elbow grease.

If G3 is taking too much effort then sand the scratches down lightly using very fine grade wet and dry sandpaper (1600 grade is ideal) and plenty water (ie hold a soaked sponge above the area and squeeze water out at all times thus giving a permanent slow water flow). Be VERY cautious not to be too ambitious and end up sanding through the lacquer. Once your scratches have almost gone then polish the area using the G3 and shine up. Repeat as necessary/as much as you dare without going through the lacquer. A tip is also to "blunten" the sandpaper a bit first by sanding something else for a minute or so.

From a timescale point of view it took about half an hour to remove all scratches from one complete side of a Ford Fiesta (which had been dragged along a "hard" hedge. My Fiance was well impressed - it looked like the full side needed resprayed before we started.
