My bet is that your window is going to hold forever with such a meticulous approach to the fix. Well done, Bob.
So if your rag top is in reasonably good shape, this is fifty bucks well spent.
OK. Just finished with repairing my top carefully using Bob's advice (i.e. prep and prime) and feel confident the fix will last an extended time, maybe forever, even in the Southern heat. The repair feels solid and looks good as new.
BTW. My top had separated at the top of the window. Fixing the top of the window is probably infinitely harder than correcting a separation at the bottom, because the glass needs to be lifted into position, rather than simply supported from below on a couple of towels. If trying to fix the top, consider using a suction cup (borrowed from your GPS mount for instance) to help hoist the glass upward and forward into position. Fashion a handle to the cup (I used a vise grip) and 'jack' the glass up into place using some scrap wood falsework supported by the convertible top frame.
Again, carefully and thoroughly clean the old glass, use the 3M One-Step primer and the Window Weld as instructed by
mach2plus Bob.
It does work. There is a fix.
