Hi board,
I noticed today that the rubber seal around the top left corner of my windscreen is lifting away slightly on the roof side. The seal itself is firmly attached around the windscreen and body in this corner, it's just that the very edge of it that is supposed to lie flat on the on the roof is instead about 1 mm separated for an inch-long section, just in the corner. I've pulled it back a bit to check what it looks like underneath, where the seal is attached to the flange around the windscreen, and it looks fine - its firmly seated, and the channel is clean and free from rust.
So, I was wondering what to do with this. I was thinking maybe use small amount of Sikaflex 291 to stick the seal to the roof, just along the edge of the seal where it meets the top surface of the roof, without getting Sikaflex deep down into the channel around where the seal is actually attached to the body and the windscreen. I am assuming that this is designed so that if water does get between the edge of the seal and the roof and down into this channel, it is supposed to be able to drain away down the channel, down the side of the windscreen (A pillar) and exit at the bottom of the windscreen. If I really go over the top with the Sikaflex and fill up the channel in the top corner, any water that gets into the channel along the top of the windscreen will get stuck at the corner and have nowhere to go, which would be bad in the long run. In other words, I am assuming that the edge of the seal that lies on the the roof is not expected to be fully water tight, rather it just deters water, and any water that does get past is actually stopped inside, where the seal is attached around the windscreen. This water will then just drain out via the channel around the windscreen. Accordingly, what I would be achieving here is really just cosmetic, and nothing to do with watertightness.
Any advice? Have a misunderstood the way the window seal is supposed to work, and is it supposed to allow drainage as I describe?
If I use something to the stick the down, I want something that will not damage the paint, and will not be so permanent that if the seal or windscreen needs to be replaced in the future, it can't actually be detached without damaging the paint. Is Sikaflex 291 the right stuff for this job?
