I knew this was coming at some point. My car is parked under an awning but outside. Only 60k miles on the car, and not seeing any winter here in Miami. I was washing today and noticed bumps under the seal on one side. The other side is not showing anything yet. I'm hoping I caught this quick enough to do some micro surgery without pulling the windshield. Any thoughts?

Pull the windshield. Not difficult to have done. Buy a new seal and after paintwork is done, tops it back in.

The water btw, migrates in from the top and settles at the bottom of the channel. So there really isn't a good way to prevent this, short of replacing the window with a blued in 993 window and the accompanying 993 seal.

I just had this work done on mine and I agree, pull the glass and seal and make sure you catch all of it. My bodyshop found rust further down in the channel that wasn’t showing around the seal. My car also hadn’t seen salt but washing these cars with water and exposure to rain is equally as bad since it’s a poor design that retains moisture. If there’s any other touch up work needed now would be a good time.

Agree. Take the windshield out. There might be more rust than you can see now. This is part of what was found under my window seal a few years back:

+1 pull the windshield. The issue is not what you see, it is what you don't see.

Ok makes sense. I'm going to need to find the right shop. The exposed paint is original and I don't want it disturbed.

I know there's another new windscreen DIY topic started, but I had the same issue long time back that required a glass-out full repair and new scuttle section welded in. The key advice I had from the guy that spends his days fitting classic Porsche windscreens, is only ever buy OPC windscreen seals/rubbers and never buy from other suppliers - they never fit perfectly which then allows water ingress back into the scuttle area. Years down the line you are back where you started.. The only other good advice I was given from a 964 specialist was do what you can to find a windscreen fitter with classic experience and not the regular company your insurers insist you use.
