Question for those that have replaced their front windshield

In 2011 I had a stone fly into the glass from a truck, and the glass was cracked, so it had to be replaced. I found an indie with a good reputation on the 993, I had them remove the glass, I had their bodyshop sort a stonechip in the A-pillar that was starting to show rust, and their bodyshop check the apeture edges and ensure all was sealed.
I then got the insurance company to take the new glass to the indie bodyshop, where the indie supervised and helped the insurance standard glass installer to put the screen in the correct place in the apeture.
So as mentioned by the other guys above - you need someone involved who knows that the screen has to be located correctly.
What weatherstrip you fit afterwards is of no importance whatsoever.
I would also strongly recommend filling the channel afterwards as recommended by Porsche in TSB 9501, but I would ENSURE that the screen is installed and set, and located correctly/centrally before doing that step.

You'd think so wouldn't you? But in this case, due to the poor drainage design of the aperture, you have to take care otherwise the aperture rots out completely from inside out. By the time it shows on the outside, you have a big problem underneath.
Specialists who can fix awkward rust properly are few and far between. Prevention rather than cure make a massive difference in the case of the 993.

Yup, I replaced the windshield on my 993 when I did a 3/4 respray about five years ago. The creaking is driving me crazy. I’m finally going to pull the windshield this summer, and have another go at it. You really need to find someone familiar with 993’s. I had a solid glass guy, but he was not familiar with the car.

Following a stone chip and crack I had my front screen replaced by Autoglass (biggest screen company here in the UK) courtesy of my insurance cover. The guy they sent struggled to get the replacement screen to fit and so he called on a senior colleague to help. They were here eight hours but were not happy as the fit was not good. They called their mothership who eventually agreed to source a genuine Porsche screen rather than the generic one they were trying to fit. Their cost to get the Porsche supplied screen was x4 what their normal supplier charged but they took it on the chin. They came back two days later and had the screen fitted to their satisfaction within 15 minutes!
I asked them what the differences were between the screens and they said the Porsche one was a few millimeters wider so just dropped in. The generic was the same shape but slightly smaller which meant they could not get it to centre or seal evenly.

My car's front windshield is original, but has enough pitting that it would qualify for a no-charge replacement under my State's insurance laws.
I am on the fence as to whether to do it or not.
I pulled the window trim and the channels are pristine, no sighs of any rust or corrosion.
My understanding is that the old window would be cut out, which in turn would cause the finish of the channel to be scraped. That in turn would make it susceptible to rust.
What about having the shop tough up the scrapes and waiting a day before installing a new window?
I guess there is always the option of sealing the channel after window replacement?

safe visibility is the point here - I think this issue gets overblown a bit and clouds the main issue - rust in those locations can occur with original glass also.
If its pitted enough that it qualified it is probably like mine was. That made driving to and fro work particularly dangerous living west of my work near sunrise or sunset. The windshields main function is providing a safe view forward. There have been times when the glare driving into the sun is genuinely dangerous and easy to missing a deer, cyclist etc. something i dont want to risk

I've also been having an unbearable creaking issue with my windshield as well. Any bump in the road makes a creaking sound. My shop who does all my 993 work says I need to get it re-sealed by a windshield professional. Have any 993 owners had any good experience with this in NorCal/SF Bay Area? Most of the ones I called are the mobile type and they all said there's a high chance they might crack my original windshield.

Porsche Fremont has a lot of good reports here on the forum, but they quoted close to $4k.
I’ll let you know what Safelite charges me for OEM glass and my participation in the process.

I got a nice smiley face on my windshield so I took it to my body shop since I have a bit of rust at the base. The thing that surprised me is that the factory windshield was only couple of hundred dollars more than the aftermarket.
I thought it would be worth knowing.

Removed/installed 1st time windshield due to bodywork (sunroof / rain gather delete), next time replacement coz of to much pitting. Than a rock from a truck hit and it got cracked.
As i was pissed already with the work from the (otherwise) reputable workshop, i gave it to the Porsche bodyshop, which forwarded the car to the Audi bodyshop ... but what to say... perfect work!!
I forgot that the insurance might pay for a cracked windshield, and so i send pictures and invoice to them post repair, just to see what happens (without many hopes)
To my honest surprise, they payed (despite that i didn't had agency repair) everything!
Result: satisfied customer!
