993 rusty screen surrounds.

[mrporsche]

Morning,

I am currently having a 1995 993 painted, they have removed the rear screen and the area where it sits appears to have acted as a collector for water. It has not damaged the metal but it is orange.

Is there a drain that is blocked, does a drain need putting in or is this just a design fault ?

The windscreen has a blister on the scuttle 1cm square so that is coming out later this week, am i likely to find a horror story, is there an issue with drainage here as well ?

As is the case with all resprays we agreed a price but have already gone up another 8 hours, and the front screen isn't out yet !!

Thanks

Bugger !!

Assuming you have gone to a company with experience of Porsches, particularly 993s, they would have known that they might encounter this issue, and the appropriate fix.
As part of a full repaint, it’s not normally a big job.

Design fault.

Same design fault.

Easy for me to be a smartarse in retrospect, but this is well known and the 1cm rust spot at the front should have had you looking for the few Specialists who are really good at this. I was lucky that when I had the front screen out, as it had cracked, I got Camtune to inspect/clean and supervise the refit of a new screen, and there was no rust.

Autocraft at Kings Langly? rings a bell as someone who knows how to do this properly.

The blister was pointed out to them, they noted it and costed a repair and repaint for what that may be worth.

Will let you know what it looks like when it comes out.

It is the second porsche they have painted for me, the first be an early 991, that came apart really easily with part numbers on every bit. This wasn't as easy mainly due to age and rusty fasteners

There are two socket head bolts holding the wings on just above the doors, i had to remove the door to get at them !! There was no rust showing at the scuttle area where they are covered by the wings.

The engine cover and spoiler were the hardest parts to get apart, really fiddly to get at.

You may find it is just surface rust and not gone too far.

Mine cleaned up nicely

Worth getting Paul @ Glasstec to come and refit the windscreens for you when ready, he's done loads of them (including mine) and puts some kind of silicone in the gap between screen and the rubber to prevent water ingress - known design fault as mentioned above or one of the other threads recently

[stichill99]

Rust treated with rust killer and then epoxy primer

And then painted to match

Does he? I wonder where he got that idea from?

[n12maser]

...something like that.

His attention to detail is covered here http://www.glasstecpaul.com/problems-with-a-porsch...

Apologies for not including a few smilies in my previous post, to help explain my meaning....

It was Porsche themselves who recognised this issue and produced a fix for it sometime in 1995 - TSB 9501 - where they instructed their OPCs to fill this gap, between screen-frame and windscreen aperture, with a specific Bostick sealant.

Whether or not the diligent OPCs ever did this task is another matter.
