Rear window and Seal water run off

[smtk]

My car has a few rust bubbles on the rear window, while down at Early911 I mentioned it to them and they had a look When they pulled the rear window seal up and there was water sitting between the glass and the chassis. When I got home I took the seal up and removed the water however it seems the water still gathers there after washing. I'm wondering if there is a clogged drain somewhere or another reason for the water getting in Cheers Simon

Run some Waxoyl or similar from aerosol under front and rear seals and repeat every Spring and Autumn. Thats what I do and it displaces water and slows any rust down to a crawl.

I have some waxoyl coming i'll give that a shot but did porsche put in a drain it there seems a silly over sight

 

[John Maddox]

Can't recall seeing any drain - anyone else know ?

Yes. If you're talking about the bottom corners of the rear window, there are no "˜drain holes'[] - it's where the water tends to sit under the rubber seal at these corners - so it's somewhere to keep your eye on; it can appear on even the most pampered car. If you've got any rust starting there, I recommend you have it sorted ASAP (i.e. not always, but probably window out, clean up, protect and repaint).

The starting of this rust is promoted quite often when the screen had been out previously and care had not been taken to replace it, in a similar fashion to the front screen "˜problems' well documented before on this forum.

smtk, don't worry if your seals sit off the bodywork & bulge after you spray Waxoyl under them. Leave them overnight and in the morning, they will have settled down as normal again as if by magic. Mine did!

I'll give it a go once the waxoyl shows up and try to take a few shots for future ref'

I what have never of found the water sitting there if Nick Moss hadn't pulled up the seal as i would have worrried about sticking it back down

Just had mine repared and screen replace with after market seal, did not refit outer cover as i was informed by the paint shop that the problem will reoccur, looks fine and now the water can evaporate correctly

 

[smtk]

do you mine me asked the cost of the repair?

 

[TRW40]

I am amazed that the water is simply expected to evaporate. When you say it can now evaporate correctly, do you mean that it is now more open to the outside air? I presume the same problem applies to the front screen ie lack of drain holes, hence the common problem with the scuttle.

When you say "pulled up the seal" what do you mean?
Just grab it with fingernails and pull at 90 degrees to body/glass?

And does it simply push back into place?

Yep the seal looks to be a simple push fit its not glued down. I could get my finger nail under it and take it up then just push it back down.

John, what Waxoyl product do you use for this sort of application?

Thanks in advance

I use just the Waxoyl aerosol spray from Halfords. I have also recently been using Dinitrol 3125 from Frost - have seen this in larger Halfords stores too. This is better than Waxoyl but is almost black so suitable for darker colours - mines Iris Blue

 

[timandlisa911]

The cost of the repair was £400, a very good job including blending in (polar silver)

I leave my front and rear window seals slightly raised at the corners to give it a chance to dry out. I am contemplating cutting a couple of small holes in it to allow water to evaporate. It looks like a major design flaw in my view. Many 993s seem to rust here for just that reason.
