Rear Rocker Panel Paint Fix Ideas?

My bumper got smacked in a parking lot and it messed up the paint on the rear rocker panel. Instead having the body shop repaint, I was thinking of black plastic dip, bed liner, or some sort of stick on rocker panel cover. EXPEL might work but it get's mixed reviews on Amazon. I got good deal on 2013 bumper off craigslist but need to protect the paint.
Any ideas out there?


And here is the rear view.

 

Are you sure where the bumper mounts to isn’t bent?

I would have the shop repaint it.

I’m not sure if you are wanting to do full rocker panel wraps or Line-X on both sides of the truck or you are talking about spot fixing it with plasti-dip.

Plasti dip will help you decide if you want the full rocker panels done but I would not use that as the permanent solution. Plasti dip just ends up looking cheap.
I’d go Line-X on the rocker panels

 

Fix the bumper n mounts n respray it. At least get it reprimed before wrapping

 

Thanks for the responses. I'm going to try to repaint a small section with Dupli-Color. It's an 11 year old truck, I hardly wash it, take it through mud, so no reason to keep it pristine, especially for the quoted $2,200 and my deductible is $1000.
