New windscreen on the 993

[Mario149]

I'm having a new windscreen fitted tomorrow by Autoglass on insurance due to a lovely big chip/crack picked up on the motorway. The car is at Porsche Torque for a few bits already, so they'll be doing the work there and I won't be around. With my paranoid hat on, are Autoglass "qualified" to do it? When I had one done on my F355, it was quite a specialist job (required dash removal etc) and Aufofficina had to get special people in to do it and there was still a bit of damage I noticed that had to be rectified after.

It's quite straight forward in a 993, just wipers off, dash doesn't need to be removed.

Do a google search as 993 screens are known to creek so you can have Teflon tape applied to help reduce this.

Worth also checking for any corrosion around the screen from previous glass replacement etc whilst its out.

As above the windscreen will most certainly creak unless fitted properly.

Also inspect the finish of the bonding from inside the car. Unless it's finished to a neat standard it can look unsightly.

Mate, prepare yourself. The 993 windscreen can be a whole lot of trouble. Not knocking autoglass, but I have heard and read horror stories about the national companies cocking up the refit on a 993 screen.

You should have gave a headsup on here first. GLASSMAN is the fella you needed. He had to supply a new one for me, as the squeaking one I got him in for to stop squeaking, had been so badly fitted previously from a scuttle repair, that it was shot.

Thanks for the info guys. I just spoke to Sid at Porsche Torque and he's going to make sure they do it within sight of him so he can keep and eye on it and then check that's its been done properly afterwards. Fingers crossed!

As already mentioned,the film to stop it creaking is a must. Done properly you'll have to look hard to notice it too - I've seen a few which were a bit iffy!

When/where does that go on, and what exactly is it doing?

You'll learn all about this kind of stuff when you become more experienced Glassy!

[zap mc]

who diagnosed it needs a new screen?

would it be the people who are fitting a new one?

hmm?

If it has a big crack then fair enough but if it is just a chip then please be aware that it can probably be fixed to a standard better than you might expect.

maybe postpone the fitting and post a pic of the chip to avoid having the optional footwell jacuzzi fitted.

I don't know if it's classed as Teflon or not but Porsche sell the clear tape that goes around the windscreen aperture that can usually be seen just under the edge of the outer rubber seal. I had some paintwork done on a C2S and got the bodyshop to use their usual fitter (I've no idea who) to remove the screen and replace it afterwards, on the proviso that the tape was replaced (it had been removed to paint it of course) and there was no noise or any issues with it at all afterwards.

I had a terrible time with one of those large outfits. 5 screens later they agreed to pay OPC to do it, who got it right first time and no tape used.
OP is probably in for a headache.

Wouldn't be surprised. My motorbike died on the way to work this morning so today is clearly not my lucky day!

IMHO, there is a massive misconception about Teflon tape/helicopter tape/etc. Porsche recognise the issue and the clue is in the product description: 'insulating material'. I've also seen some neoprene-like chords wedged in behind the trim assembly; again, it is serving a purpose because the real cause of the creaking was not identified, but stuffing a length of rubbery boot lace cured the problem without really targeting the source.

If the creaking exists, or the cause of creaking has not been addressed correctly, the insulating material will do what it says, and that is insulate against the vibration. The majority of fitters/installers do not understand what exactly it is that's causing the sound and in some cases, it is this ignorance that further compounds the problem.
