Doug,my issue is similar to yours;just the driver's side. It's looking like your solution might work for me. I'm fortunate to know a couple of good metal shapers that could duplicate the panel. Got any pics of your fix? I've noticed some brown spots by back window as well;I'm hoping that full channel replacement is NOT in order. Lately I'm finding lots of sh!t;my mood is souring. My issue:
BAD place;I don't foresee much driving on potentially rainy days... What a fix;the blue Permatex is a nice touch,don't you think?
Stan;where are you going with yours? Keep us informed,please;I'm sure a lot of this group can both help and benefit from this thread.
