if the pillars are damaged, then there is no other alternative to repaint. I suggest that u upload some pics for a better assessment of the situation.
For dry-denting(no repaint), I recommend Ustaad Mehnga. My 06' Mehran was damaged in 2009 by reckless bike rider. The damage was severe and many denters suggested a repaint. I went to Ustaad Mehnga as he was recommended by an Uncle. He managed to pull it off marvelously.
For a proper paint job and flawless denting, i recommend Javed Autos. A frnd's '10 Coure was involved in a really bad crash. The front frame beam was pushed inwards about 6 inches and the hood was badly damaged including the front bumper and headlights. Javed Autos did a marvelous job n it doesn't appear to be damaged at all.
Do give them a try.
