I am about to try JB Weld. It's too late to save my bezel -- but the glass liner peeling away actually makes it easier to get to the frame part and clamp it with a C-clamp. Do I think it will hold? No. But the only alternative I've heard is to get a repair costing upwards of $500. Given the age of the MBP, I'd rather invest $500 in a used 2011 or 2012 era machine and not risk this happening all over again. You're right, the engineer who indicated the drill holes -- probably some guy in China looking to save RMB -- obviously never designed a laptop in his or her life.
