Although can't tell much just by looking at the picture, I think that dry denting will suffice but from an expert denter.
An honest suggestion, NEVER go to the dealership (stealership) for such kind of work as they will just rip you off and most of the dealerships don't even have a professional staff. It is advisable to consult some professional workshops for this kind of work.
Most definitely YES as long as you will consult an expert denter.
I suggest you go to the Zaheer Denter in National Market, Satellite Town, Rawalpindi, and I'm sure that he will provide you the best solution to your problem.
Hope it helps.
