@Lolly: Unter den von Dir beschriebenen Umständen würde ich in der Tat dann auch mehr machen, als ich vorher erwähnt hab.
Hier noch was zum Thema neuralgischer Punkt an ner C3 bzgl. Windschutzscheibenrahmen und Rost, allerdings auf Englisch - bezieht sich auf Vergleich mit C1 und C2:
The C2 windshield installed the same way as the C1. The glass was ‘wrapped’ in a rubber gasket and the rubber gasket was ‘shoved’ into the windshield frame making an interference fit inside the surrounding steel frame.
C3 and later cars used the ‘lay-on’ glass technique which is how all modern cars get the job done. The glass lays up against the windshield frame riding on a ‘bed’ of urethane glue. Installation is a LOT faster, and if done correctly, it’s a fine system.
The problem with the early Shark cars is this was a ‘first’ technique and nobody really expected these cars to have a +50 year life. They had problems because other things that surround the windshield attach to the windshield frame with screw (molding clips, header trim, Etc. If you closely study a Shark AIM, you’ll see there’s a myriad of different sealer ‘glues’ used here/there to thwart water from invading the windshield surround.
The reason why early Shark cars are particularly prone to windshield frame rot is that you have to remove various trim pieces (bye bye factory original glue/sealant) to get the old glass out and those not trained by GM to service the cars (best price for replacement glass is typically from small independent shops) weren’t aware of the importance of replacing the factory original sealant(s).
Plus, when the leak(s) happened due to their ignorance, water did NOT invade the interior of the car (customers would have immediately complained). It ran inside the windshield frame and down the bird cage where it puddle and ate away at the INSIDE of various birdcage components. This is almost NEVER the case for C1 or C2 cars.
With the early Sharks, the only way to tell if there’s a problem is to strip all of the reveal molding from the windshield and visually inspect the integrity of the frame. Very few novice buyers understand the threat/issue and wind up buying these ‘basket cases’ out of pre-sale inspection ignorance...
