I scratched my car with a shovel when cleaning up the snow from the winter storm in DC. I read some posts on the forum and it seems that I could use Quixx Care System or Nu Finish Scratch Doctor. I attached a pic of the scratch because it seems that depending on the scratch, it can be fixed or not. BTW is it the only thing I need to fix it.
If those 2 don't work I think your only option is to use touch up paint and then try to blend it in with a good rubbing compound.
