Just got a new sterling gray metallic mustang and a small pin head sized chip on the front hood. I have both dr color chip and langka kits I bought about 4 years ago and have never used. My questions are:

Should they still be good if never opened/used?

Any feedback or tips on using either for a small chip based on your experience with either one?

I would be using touch up paint from the dealer. Thanks!
