Roof to Side Rubber Seal Cracking/Peeling

Thanks Steven for the reply,I think I found the right replacement seal on Amazon. Will give the replacement a go next week when it arrives.

If I recall correctly, the bulb and wiper are in a track and it would likely be easier getting the old one out of that track than to get the new one in. However, I don't think it is too awfully complicated. Search Amazon and see if any of those are a match for what is there.

+1 It's a quick job and not difficult to do. A 100' roll will do every seam on a 179.

I did mine a few years ago but also changed out all the steel screws to stainless.  IF you are only doing the 1 inch vinyl trim and nothing else I cannot imagine it taking over 2 or 3 hours tops.  The only part that takes much time are the ends that have the Phillips head on the black plastic cap.  Those need to be cleaned and re-caulked.  If the temps are warm enough so the trim insert is flexible it goes on very quickly, just squeeze it together and let it set in the channel.  Again, the pieces on the slide out take a bit more time as there are 4 corners, Phillips screws to clean up and re-caulk, but overall it is quite simple and straightforward.

Okay, it is the vinyl strip. 3 years is not bad. If it were less than a year, you would have a case. Sun, heat, and weather is not kind to the factory strip. Just order the vinyl strip about which I posted which costs a lot less than what you quoted. It is $26.50 US. Even with the exchange rate, it would be much less than $150 CA. That is, unless the import duties are that onerous.
