Hi Uncle Steve,

Take a look here:

Take a look at my images, also. The 1992 240 GL I bought in August 2008 was a real mess under the windshield. A prior windshield replacement and exposure to CO-state elements caused holes in and around the pinch weld / windshield pan.

IF it is an original Volvo windshield with butyl rubber (See the Volvo name and a brand such as SEKURIT (Saint-Gobain), Trempex, Sunex, Scanex) and adhered to the windshield pan using the black and tar-like butyl rubber tape, you can remove it yourself using a windshield gasket cutting wire. If it uses a pink or other color gasket that is not sticky, it is a urethane gasket and you'll have to call an auto glass tech with a hot knife or other tool to remove the windshield.

Remove all gasket matter.

Hopefully you have no rust through holes like I did. Either way, follow the POR-15 or similar process for a cold rust repair. If the corrosion is so bad you feel you need to weld in new metal, well, you may have to enlist a body shop as you have to seal up all raw metal including inside the A-pillar and other blind compartments around the windshield pan and pinch weld.

Windshield replacement using a auto glass tech means they'll use cheap Chinese auto glass and urethane adhesive gasket matter. IF you have to replace the windshield, remove may damage your rust repair.

I got a crappy "Pilkington" brand piece of China auto glass crap for around 90$. It has a plastic border on it. Into that plastic border you press in a plastic trim to hide the gap between windshield edge and pan. It never stays in on my 1992 240 GL. It is a mess. In spite of replacing like several dozen windshields, mostly on Volvos, I got this a little misaligned to the drive side by like 1/32" and it has been a real pain with the stupid trim always seemingly coming out. So I use some black 3-M adhesive. I have to use more.

Chinese glass is crap. It is thin and soft and not so clear. The laminate bond layer between the glass is not very clear.

You don't mention your year and model Volvo.

For 240s and older, you can't get auto glass from Volvo or the aforementioned auto glass manufacturers (all from Europa, of course).

Questions? Comments?

Good luck.

MacDuff.
