Well today was suppose to be the day i get my windshield replaced and my rear window weatherstrip replace.But when the windshield and trim was removed we found some (minor) rotting and the we went to the the rear window that also had (minor) rotting. What can i do to do a quick effective fix.

 

That'll have to be sectioned in with new metal.

 

Yeah the only way to fix rust is cut it out and weld in new metal.
