How should I repair a dinged up LCD screen case?

The Macbook Pro 13" LCD display is hard to dismantle. With the iBooks and PowerBooks and even plastic macbooks models it was easy to swap the panel case, only 2 or 4 screws to unscrew and the job was done but with the unibody MBP 13"/15"/17" Apple made it more difficult. You need to heat the glued front glass to take it out and have access to the screws that retain the LCD screen. Doing this would probably void the warranty if you still have one and you could also damage the LCD if too much heat is applied to the screen. A complete LCD display swap would be more secure but would also cost much more.
