Rivets working up through glass on nose

Re: Rivets working up through glass on nose

I'm with Joe Lucia on this one... I don't see how slobbering a form of penetrating oil onto the reinforcement bar & rivet heads is going to arrest the process. It looks like you understand this is a dissimilar metal + oxidation issue. What leads you to think a thin and spotty coating of oil is going to form a perfect air barrier to stop oxygen from getting to the metals involved?

Hey now Not every car is going to have this issue so don't assume that if it doesn't have rivet bumps its not original corrosion is corrosion it has everything to do with how the car was treated.

I bought a original nose from a 68 that had alot of rust on the steel parts but the header bar did not have any rivets pushing through the surround glass.

Re: Rivets working up through glass on nose

A good restorer I know in Western Maryland made an observation that explains some of the randomness of rivet bump development. He said that the thickness of the bonding material between the header bar bonding strip and the surround panel varies car to car. Those with thicker glue layers have more room for the corrosion deposits, and the bumps take longer to develop and even may not develop.

This makes sense to me. It seemed to me that 69 & early 70'S that I looked at with original paint had less bumps than later C-3'S
