Paintwork repair options
If the scratches aren’t too deep, you may be able to buff them out or reduce their appearance using a DIY scratch repair kit. Bear in mind that this won’t be a professional finish though, and you’re unlikely to be satisfied with the results if you really want good-as-new paintwork. You may even make things worse, so only attempt it if you know you have the expertise to do a good job.
It’s only worth going down the DIY route if the scratches haven’t gone too deep. If you can see metal underneath the paint, it’s probably going to need a professional touch. Deep scratches down to the metalwork will expose the panel to rust and corrosion, so it’s important to get this fixed even if you’re not bothered about the aesthetics.
Hiring a professional to sand down the scratches, re-prime the panels and apply a fresh coat of paint can be pricey. But you may find that some, or all, of that cost is covered by your insurance.
