With water leaking through the rear quarter windows in my '68 Amazon Wagon, I decided to try replacing the gaskets myself.
Taking the old windows out and fitting the gaskets and even installing the windows back into the car went very smoothly...apparently too smoothly.
I can't figure out why the gasket formed "waves" at the corners.
I've tried manipulating the gasket to no avail. it is like this in each corner. At the end of the weekend I had to give up and just squirt mastic in there so it wouldn't leak (it's my daily driver and doesn't have a garage to live in at the moment).
Any idea what I did wrong or how to fix it?
