About 3 years ago, I repainted the interior Medium Slate Gray painted surfaces.
Got a small can of Chrysler D5 (Medium Slate Gray) from TouchUpDirect.com to do the job.
Used a foam brush to cover the scratched and stained surfaces.
Looked "new"" when done.
Also, it's water based so it's easy to clean up and "fix" errors before it dries.
Cheers,
