My friend owns America's auto body 847-985-3760 (Schaumburg),the guys wear white lab coats and the spray booth has glass windows for customer viewing.You can not be treated better or pay more!
There are great shops everywhere,probably down the street from you.Setting up the best relationship with the owner and/or painter is the true trick.Stop out at UNO's in Schuamburg on Thurdays,Supercarschicago group.
