65 Barracuda daily driver

I still don't have much time, but I test sprayed one my old door panels with vinyl paint. I have some that are in much better condition, but they have all this dirt burned into it. I'm pretty happy with the results - the photo does not do it justice. Hopefully the next couple of days I can spray all 4 of them. I have another issue, though. While driving the doors are rattling a lot. Do you guys have any ideas how to fix that? I already replaced the fabric that is on that door opening rod and I think it will get better once the door panels are on, but I find it very annoying and would like to eliminate it.
