I may have brown eyes, but I had a 30 year veteran windshield installer tell me that 100% pure silicon can actually promote rust on bare metal... Apparently, it's acidic.
Had a '69 Nova when I was a kid... It had the clipped & pinned chrome bezel around the windshield, and rusty as hell! Because previous owner had filled the gaps with silicon.
Cleaned it all up, primered it, and sealed it all with Butyl Rubber. Got rid of the car instead of the wife (now ex)... Still kicking myself, shoulda kept the car.
And I'll fill all my motorhome holes with Butyl Rubber.
