...I have what appears to be an outline of the trim on the door It isn't tape residue, it just looks and feels like dirt that seeped in around the edges of the trim and couldn't be washed off. Would a claybar work to get this off, or is it etched into the paint and will require other measures? Truck has 29k btw

 

Try a bottle called goo-gone its a yellow liquid and has worked well the times I have used it.

 

I've got some of that, will give it a try

 

That or some bug and tare remover but make sure you wax and wash the area good after using it or it will discolor the paint.
