I typically don't brag up businesses...but this place worked wonders on my crushed hood and did an unbelievable job at detailing my car. Dent Wizard in Schaumburg is the place. I know it sounds crazy but this place just (this weekend) completely restored my walked on hood and high speed polished/waxed/interior cleaned the 'Box.
Ask for Gary (the owner) or Phil (the manager) and tell them Paul with the Porsche with the dented hood sent you.
BTW--detailing the car can take a day and they offer a $5.00/day usage of one of their loaner cars to get around. Cant beat not having to get picked up and dropped off by the wife/friends!!
