Get them cleaned thoroughly - especially the areas at the bottom of the door. Clean all the drain holes also. |
I have just changed the window seals on my 1982 Mercedes W123. And yes, all rubbers on a car will deteriorate over time. How quickly is impossible to predict. Depends on many factors. Quality and the type of rubber, age of the car, the environment the car is in, whether it is parked in a garage, exposure to sun light etc.
Personally, I think parking a car in a dry, well, ventilated garage is the best. Not just for rubbers, but the car as a whole. Think paint, electrical wiring etc.
What i have noticed over the years is that similar rubbers might appear to be wearing at very different rates. Out of the 4 window rubbers on my Mercedes, one was really poor, in one corner. Two had a bit of wear and one still looked quite ok. So they all appear to wearing at different rates. When I took the off, the underlying window frame had similar signs of rust. This is the thing, as soon as a rubber starts perishing water ingress starts happening. Even if the rubber might not look to bad, the metal underneath is likely to start rusting. https://www.team-bhp.com/forum/diy-d...ml#post4607318 |
