thanks for the links
btw, are you guys dealing with this...
Where the heavy rust is seen on the seam is exactly where I would see water form and roll out from under the windshield rubber. No problem since the new rubber, buytal, and glass. I am going to check Seapotato's suggestion too, as a preventative measure.
As to your earlier question Gold Boy, I don't think the wax oils will be an issue.
