Leaking sun roof

I am looking for advice from anyone who has replaced the seal on the removable roof panel please.
Am I right in thinking it is just a case of peeling off the old one and fitting in the new one?
I seem to remember a post on here where someone had to trim the new seal as it was too long!
Any tips before I commence would be much appreciated [:)]
Fed up with damp patch on back seat! [;)]
 
Hi Martin,

Did you get my reply?

I never changed mine as, sitting in it in a rainstorm, nothing was coming through. My only comment was that the genuine ones shouldn't be cut, but it's so cold at the moment it's not going to shrink much more!
 
Yes it just peels off and pushes back on and its probably too long , however like the hatch seal REALLY make sure its pushed on and not stretched as it will shrink and leave a gap!
 
whatever you do, do not cut it down.

clean the drains with strimmer line as it wont damage the drain tubes
 
I purchased my last sunroof seal from Frazerpart. This is listed as genuine, however you'll need to cut it to make it fit. It has a metal reinforced channel moulded into the seal and no amount of "pushing it well into the corners" will loose the extra inch I had to cut off. Remember the roof panel is fibreglass and the lip the seal attaches to is fairly thin and fragile so I wouldn't suggest being too rough with it either.

Precisely my experience too, despite reading all the advice about not cutting it down I found that it was necessary. I confirmed this with Max at Frazerpart before trimming it.

It's not quite an inch that needed to come off, but most of an inch. And don't use opposing shears (i.e. tin snips or the like) to cut it with as you will crush it. I used a dremel with a cutting disk, which worked fine.

Thanks to you all for the very useful tips and hints. [:)]
Job done with a small trim needed. Quite a tight fit when it closes now, in fact needed a bit of encouragement but I guess it will ease up with use.
That'll be next Spring then!
 
I bought a genuine one from OPC and it was very tight but did not need cutting down..... it was about 15mm too long on first fit when it had been massaged about it went on without cutting.

Like Oli and yourself this was exactly my experience. The seal they sold was far too long despite it being listed as 'genuine'.

Some may disagree here but I sort of wish I went with the Porsche item now!

Out of curiosity, why? (Other than the fact that you have now sold the car!)

In short, I wonder if it would actually have fixed my problem! It is not the first time I have had issues with pattern parts. To cut a long story short the roof still leaked in very heavy rain(albeit less) despite the drains being as clean as a whistle. After shelling out a small fortune on the seal I was not prepared to spend that amount again despite checking things thoroughly (Like a few here I kept a bit of excess on so as to ensure that the seal did not shrink and leave me with a gap. I guess my old seal was shot (it fell off most of the time I took the roof panel out so I guess there was some improvement!).

FWIW my 951 leaked right at the front corner from the hinge. I guess the leak may have come from the windscreen but surely the panels before that would have shown signs. Water ingress from previous experience is one way to ruin a perfectly good interior (along with the smells of stagnant water) in addition to aiding tinworm.

I know that on my Stag (where I was initially annoyed that a seal went 'missing' after a trip to a specialist) there was a gulf in the difference of quality between essentially the same seal (in terms of fit and actually keeping water out!) but it did require alot of homework, although some peeps in the know did eventually spill some secrets thankfully, instead of forcing you to buy their products thankfully.
 
I found that if the outer seal leaks loads the inner one then starts to do a kind of syphon / capillary action then leak inside, replaced both and stuck the inner one on with the channel in the seal filled with clear bathroom sealant, that stopped it leaking
 
i did wonder whether the inner seal was causing a leak but it did look OK. I guess if it was slightly perished that would also cause a leak.
