968 hatch question
So, does the 968 coupe hatch glass inherit the same glass separation issues of the early hatches? I've got big time hatch problems with my early 944, and I am planning to buy a new car anyway, thinking about a nice 968 coupe, but I notice it has basically the same hatch.

AFAIK, yes. As mentioned, they're newer, so prolly not as much degradation. Remote possiblity the support struts may have been modified with less pressure; my understanding is the struts have contributed to separation when the laminating glue degrades and the struts "pull" on the frame/glass. Not sure, but the "wing" on the 968 hatch may also be lighter than the earlier rubber spoilers, which may have allowed for lower pressure struts. IMHO, if you have an otherwise perfect hatch, disconnecting the struts, even temporarily now & then, may help its longevity.

I just went through this with my 86 951 and 94 968 hatch (yes, I have both.)
My 951 hatch was completely delaminated at the top of the hatch. I took it into a local Safelite where the first estimate to simply apply some adhesive was $80. Then when the car actually arrived to them and they got it in the shop they determined it was going to take much more than simply shooting in some adhesive. The price went to $200.
They removed the hatch from the car and had to completely disassemble the thing. This meant not only removing the bat wing and trim but also separating the glass from the hatch frame. They told me that back in the day they NEVER did this as an insurance replacement would simply replace the full hatch frame with glass. It took the 20+ yr esperienced glass guy a total of 5 hours to separate the glass from the frame.
I was told what had happened was the black strip around the edge of the glass had disintegrated due to UV exposure. As this black strip, referred to as "primer" disinegrated the adhesive let loose with the result being delamination. I was also told it was standard procedure back in the day to paint this primer on but on today's cars the primer is baked into the glass. Consequently new glass does not delaminate.
So with the glass removed from the hatch frame the old primer was stripped off and new primer applied. I was told the new primer, due to advances in primer/adhesive technology would probably well out last the car. (that doesn't come as a big surprise!) After allowing the new primer to dry a full 24 hrs in a heated environment, the glass was re-installed into the frame and adhesive applied. This was allowed to cure for 48 hr in the same controlled environment.
We re-installed the hatch to the car and I was on my way. However I was told to leave the struts off the hatch for at least a week and two weeks would be better.
In regards to the 968 hatch, prior to the 951 hatch being disassembled the 968 hatch was examined to see if it was in any better shape. While it didn't have the complete delamination present, it could be seen where the primer has started to disinegrate. According to the shop, while there being a 8 yr difference in the model yr of the cars, the hatch assembly, in terms of the primer/adhesive, was the same and it was only a matter of time before the 968 hatch expereinced the same failure as the 951 hatch.
Hope this helped.

prospeed,
200$ sounds like a very good deal for the amount of work that it seems to have taken to get your hatch fixed. Considering the replacement of the original. I have been thinking of doing this over the winter, because I don't think there is a shop in Montreal that can do this. If you remember, give us an update in a few months to tell us how it's holding up. Mine is annoyingly loud now, so I have to do something about it, and I would prefer not to replace it. The hatch on my S2 seems to be a pretty rare hatch, there is no wiper arm, and it wasn't taken out, there is no hole cover. Seems it was a factory delete, so finding another one like this would be pretty difficult I think.
Has any one here done the job them selves?

@DHC6 The $200 was a good deal. They said after mine they wouldn't touch one again for under $500 and that would be justthe entry price.
@docwyte. It was the Safelight at Iliff and Havana. Talk to Chris but don't expect another $200 job if I can believe them.
