Depending on your damage. (I forget if you ever posted a pic or not), I would leave your tailgate as is.
You can attempt to fix it with the glue on tabs, but I'm not sure how well they will stay on.
The inside of the tailgate is very reinforced, and difficult to straighten.
Don't bother trying to fix it with the old school slide hammer yourself. It might be able to be fixed by a really good body guy.
I would just run a coat of paint if any paint is chipped to stop it from rusting.
Mine is still not straight, I used some washers behind the tire carrier to straighten it out.
I'll let some pictures tell my story.
The rust that started to form because I didn't do anything to it for a while.
The damage that occurred from backing up into a pole.
The attempt at fixing it with a slide hammer.
Bondo was used to make it unnoticeable. It is now cracking due to the vibrations from the tire.
Good luck on your endeavor!
