Today we are going to discuss a common issue facing consumers after they hire a glass company to install a new windshield or any other fixed glass that is bonded in using automotive urethane. More often than not during the removal of a fixed glass such as the windshield or back glass the perimeter around the glass known as the pinch weld will be scuffed or scratched. Even with extreme caution there is a possibility this will happen. This is where a good installer and a bad installer part ways. Left untreated with the primer that was designed to be used with the specific urethane in which the glass will be replaced with, the body will form rust. Minor scuffs will form oxidation that will most likely take some time to pose an issue but is still a problem. Rust not caught in time will pit the pinch weld and cause thinning of the metal surface or formation of holes in the metal causing leaks and compromising the structural integrity of the vehicle.

 

This is an example of rust that i found on a Mustang. The damage was borderline needing to go to a body shop. I was able to use a wire wheel to remove the rust then treat it with a rust converter. After the converter dried i then primed the surface with the primer to seal the surface from future rust.

 

 

 

 

 

 

 

 

I found this rust on a 2010 Nissan Titan crew cab. The same method was used to remove the rust.
