Paint Problem Options

[cal914]

Had my 914 bare metaled and repainted 6 months ago ,when washing her the other day I saw that the paint was blistering and coming away from the body where the windshield wipers are attached ,this is happening on both ,I was told by the shop that painted the car that this was due too old rubbers been fitted (there only 2 years old and they did the refit ) is this correct or are they BS me ,any advice would be great fully received

I would send that pic to the paint manufacturer and get their read on it. When they tell you the same thing people here are saying, you'll have something concrete to counter the BS you are getting from the paint shop.

BTW, why the hell would "old rubber" do this? Fresh rubber would be more likely to out gas something that MIGHT interact with paint but I doubt it. Old rubber should be as inert as it gets.

Good luck!

From a materials science perspective this is a paint issue/prep issue. Even if the rubber gasket was out-gassing the paint should be impervious to it. Every paint manufacturer is going to test their material against rubber since it’s commonly used adjacent to painted surfaces. If there was a possibility that the outgassed material could affect the paint I’m positive it would be on the angstrom level. Certainly not deep enough for the paint to fail like this, which I would classify as a cohesive failure (read: between layers) from the photos. The ‘twist’ of the painted surface kinda gives it away. Even if the paint had cured enough to cut and buff doesn’t mean it was cured enough for assembly...particularly in this area where paint would have the opportunity to ‘pool’.
