I know this is one of the acknowledged foibles of 993s as they get older.

A car I'm interested in has a couple of minor incidences of rust along the bottom of the windscreen, just underneath the rubber screen surround. The car is just over 10 years old so it's outside the Porsche corrosion warranty period.

Can anyone offer an informed estimate of the likely cost of rectification, as I have no idea what this kind of work costs? I appreciate that it's hard to say without seeing a picture of the rust spots in question (haven't yet got around to working how to do that!)but it looks like the corrosion is in fairly early stages.

As a secondary issue, can anyone tell me whether its likely to occur elsewhere once it starts to crop up in one spot? Or does the fact that there are already these two small rust spots not have any bearing on whether it crops up elsewhere around the screen?

(I've come from a background of new or new-ish cars where rust has never been an issue, hence my complete lack of knowledge about it and the costs of putting it right.....)

Ta!

Screen out, may break screen in process, I'd advise a new rubber too.

Grind down, weld new metal in, grind flat, skim and paint. Should be looking circa £200 plus rubber and possible screen.

No reason it should corrode elsewhere, my 964 did the same thing no corrosion elsewhere, took me very little time to do as I was respraying the car anyway!

Could you not claim under the warranty?

I got my pin prick (the rust, not me) bubble done under warranty. Crap paint job - cost Porsche around £500. Wouldn't have bothered myself tbh.

There is a small risk, but an experienced guy should be able to remove without breaking it.

No need for new rubber - these screens are bonded.

Just had exactly that problem fixed (under warranty though as just a whisker in under the 10 yrs) by BodyTechnics of Slough - they're the affiliated bodyshop for my local Dealer.

Afraid I can't help on the cost to get done yourself but their number's 01753 567220. Although they're not near you, they may give you an indication over the phone - they must have done plenty of these. Would have thought they were at the top end of the cost scale though...

Apparently the other place the rust could appear is around the rear windscreen too - for the same reasons as the front.

How far out of warranty is it..? since it's a known problem you may catch your local Dealer on a good day and they may accept the claim...???

I had this problem on a '96 993 Turbo 4 back in 2001 (car out of warranty). I called Porsche GB and they came out and inspected it and said words to the effect that pre 1997 model years all had this problem (design flaw), caused by the reinforced edge of the windscreen rubbers (Teflon I think)cutting through the paint and galvanisation and causing bubbling. however because of the age of the car they would not cover it under warranty.

I wouldn't accept this, played the "this is my 5th 911 bla blah blah" card and they relented and fixed it all free of charge on a goodwill basis. (Admittedly the car was only 5 years old at the time)

So Porsche are aware of this problem and despite the age of your car, it might be worth trying to appeal to their good nature. Also get them to check if the car has had the problem fixed in its lifetime in the official bodyshop network, if it has it should have a lifetime warranty on the repair.

They should have done it anyway under Porsche's 10 year anti-corrosion warranty on the 993. Unfortunately i had just missed this when i bought the car, so was planning on having mine done at the same time as the rear bumper respray this winter.

Do you have all the bodywork inspection stamps? If so, this should have been spotted when the car was within the warranty, and the checking OPC is liable. I had this problem when I bought my car, and the service book had all the stamps for the bodywork inspections. My OPC rejected my claim initially, but I persued it and they eventually said they would pay a third of the costs, the previous OPC who carried out the inspections would pay a third and I would pay a third. The total was around £1400, but this included a new screen which was in need of replacement anyway as it was full of chips. Apparently all work carried out through the OPC carries a lifetime warranty, which is a bonus.

Try your OPC, but don't take no for an answer!

I had a small corrossion patch in the corner of the screen on my 993. A local bodyshop did a great repair job and I think the total cost was around £500 inc vat.

It's definitely a windscrren out job, so I got the windscreen replaced under insurance. Good job the insurance covered it as the screen was about £500.

I just noted that the original post is from Lukin Lawyer.

By the time he buys a bl**dy 993 a bit of rust round the windscreen will be the least of his problems. Most of the 993's on the road will have practically rusted away by then!!!

I struggled to sell my car when I first started posting about 993s earlier in the year, so I took it off the market and decided to hang onto it for a bit.

I managed to sell it a couple of weeks ago so now have cash in the bank and the search can begin in earnest!

I was wondering the same! While you've been doing all the procrastinating, we've been hooning around in our beloved 993s!

Seriously, best of luck with the purchase (whenever that may be)!

Cheeky fecker!

The delay wasn't through choice - simply as a result of the fact that there's considerably more market for convertibles when it's sunny than when it's cold and rainy (as it was when it first went up for sale) and I wasn't prepared to price the S2000 to sell quickly. Now the cash is ready and waiting, the hunt is on thumbup

There is another place where there may be rust; at the bottom edges of the rear screen. It is worth lifting up the seal at the corners to have a look if it isn't immediately obvious.
