Windshield Replacement: '85 928S
Searched the forum and got some good info, and also read the manual , but a a couple of things are not clear to me.
1. Does the windshield have a rubber gasket/seal that goes around the entire windshield? (doesn't look like it has one)
2. Glass primer and adhesive: The manual mentions a glass primer and adhesive. Can I get these at any auto parts place, or would you recommend contacting one of the 928 vendors to get their recommened primers and adhesives (if they offer them)?
3. Rear view mirror install: The manual says to use: Cleaning solution, Primer, Cover sheet, Activator, Adhesive. So, same question as above. Can I stop by my local auto parts store and get necessary stuff, or do I need some specific primers, adhesives, etc?
And any other tips would be appreciated. Thanks!

1. There is no rubber gasket. There are two small rubber spacer blocks at the botoom of the glass that you must re-use.
2. Not sure where you get the primer or the urethane adhesive (comes in a regualr caulking gun tube). Sorry. Also, if you see mention in the WSM of a Porsche kit, ignore it. The kit, although avaliable, uses outmoded adhesive methods. Urethane has replaced the rope style caulk in the kit. Cleaning and primering is critical. The pros do that while the mirror dries.
3. The mirror reattachment is done with a kit available at any auto parts store.
So, where did you get the windshield? What did it cost.
I've heard of pro installed aftermarket windshields for less than $200 total. In my area it's over $300, and be careful as they are using inferior Chinese glass. I mean REAL inferior. Usable but wavy due to the low-cost manufacturing process. If you are shopping for a windshield installation, try to determine to brand they will use beforehand. PGP (South African) is OK. - Correction, it was PGI and then Pilkington. Both good. The Chinese glass was XYG and not so good but I'll live with it.

I had gotten quotes from a few different glass companies, including Safelite. I took the recommendation from my neighbor and called up Triumph Auto Glass. They originally quoted $238, but price matched a "discount glass" shop, and matched it to $198. They came out to my house and installed the new glass for $198 out the door. Also took the guy about 3x as long to install because of the old type of adhesive on the window. But now everything looks great. I would check them out if I were you! I am very happy with the quality.
"... I have just watched the pros do it. The good ones have a talent for putting down a consistent, fat bead of adhesive. "
The last pro I watched achieving that consistent bead did it with a battery-powered caulk gun. What a great tool! How hard to find and overpriced! How amazing that lots of guys who use a lot of caulk have never heard of them! And this fellow had had to buy his own, it was not provided by his employer, the big auto-glass company. I don't remember the brand.
If anybody finds a good one for ~< $50, I'd buy it.

Also, he had no trouble getting the old glass off. He ran around the edde of the windshield with a 90 degrees bladed cutting tool that completely separated the glass from the adhessive in no time, lifted the glass off and made quick work of the adhessive underneath.

Price was $555.75 - delivered to a local business address
(Glass: 375, Crating: 25.00, Shipping: 135.75)
A PacNW lister recommended them. They do ebay auctions, but I just called them up and asked if they could get me the windshield at the same price as they got my buddies, they said no problem. They were very easy to deal with. The glass arrived fine and it looks good.
So, I'm anticipating have to mechanically strip the old adhesive, and then applying some type of primer to the metal to help protect the metal long term, and also to prep it for application of the adhesive.
I'm also seeing about lining up some local 928'ers to come by and offer moral support. If we can, we'll snap some photos and post the saga.
I'll let you guys know how it goes.
Again, thanks for the info, its much appreciated.

And I just stopped into a local windshield replacement shop today and they were great. They sold me a little "kit" of the urethane adhesive, primer, and windshield cleaner. They also gave me a quick education on the process. They couldn't have been any nicer about the whole thing.
He did pointedly ask me though:
Are you doing this yourself?
Have you ever done this before?
And lastly:
Are you sure you want to do this?
Ha ha...
Total charge for the kit: $15! I gave him a $20 and said lets call it even and thanked him for all the tips.
