A few months back I noticed that I had a small issue with my paint when I had the back door opened. It's starting to be a bigger issue slowly but surely. I've attached pics with a quarter as reference for size. I'm not familiar with how to go about fixing this, but probably more than competent to do so given that its inside of the door and not in plain sight. Obviously my goal is to get it sealed up as best as possible to prevent further spreading of rust. I know some of what needs to be done, but any help and advice would appreciated.
- I know I need to clean up the rusted area. What should I use to do so and how far outside of the rusted area should I go if any when getting it cleaned up.
- I have a paint match pen for my truck. Is that all I need to use once I get it cleaned up, or is there something in conjunction with it I should use?
