Anyone know how to fix this dent on my rdx? Or estimation of cost for the damage? No idea how the dent happened and the red streaks are from trying to wipe the dent.

 

Contact your local paintless dent removal guy, should be able to take care of it for you.

 

That is a door ding with paint damage. It will need dent removal (a paintless dent repair might get the ding out) and a touchup or respray.

A touchup will most likely always be visible but a proper respray will cost $500 or so.

You can get a touchup kit yourself and see if you can live with the repair (once the dent is gone). A paintless dent guy will cost ~$100 or so.

 

Is it paint damage or paint transfer? If transfer it will come off.

 

There is seldom (never?) paint transfer in this type of door ding. The sharp impact will either result in a ding with no visible paint damage or with paint damage. In this case paint damage is visible.
