In the automotive industry, there is a RULE of THUMB. If your thumb can't catch the scratch then it can be buffed out easily using Toothpaste as it's only on the clear coat of paint and if not then you need to go out with a car scratch repair kit or repainting because it's way too deep to buff out.
How much does it cost to repair a deep scratch on a car?
The cost to repair the scratches on your vehicle depends on how numerous and deep they are. A surface scratch can cost you as little as $150, but a deep paint scratch can cost upwards of $2,500. The average cost of a full car scratch repair is around $3,500.
