Okay, this is my 1st time actually replacing weatherstripping. My question involves the roofline weatherstripping. What I need to know is: does this weatherstripping actually get glued in or does it just sit firmly in the chrome channel. The old weatherstripping came off pretty easily and didn't seem to actually be glued in place. This is on a '67 btw. Anyone that's replaced this weatherstripping b4, please help. I want to do this right, the 1st time around. Thanks!
