I am getting all the body work done on my car and need to buy the paint but we can't identify the paint code. It is scrape in the door jam area and it looks like it may be either KT5 or KJ5. KJ5 in the book was called Slate Gray Metallic (Mica) so I assumed it was that. I just need to be sure what it is called because I don't want to spend all the money for paint (90$ a quart) for no reason. Thanks in advance!
