I pulled both front and rear windshields from a coupe the method Charmalu described for pulling the back one. The windshields came out as a unit with the seals and the aluminum trim still in place and the seals were in amazingly good shape. If there is a coupe in your local yard I'd say pull both windshields, they're hard to find. Do the back one first - it's easier and you'll get the hang of it. Use flat, blunt tools (like plastic scrapers) to gently pry and lift the rubber - it's not too hard to do if the rubber is still good.

For the regular W123 some people have used the from My notes: Aftermarket Front windshield seal that someone used Precision replacemnt parts corp. WCR361

I believe it was said they are made in Thialand. There is I think 2 threads on them.

I Take a plastic dinner knife and shape it with a grinder to make a hook. Take the hook and drag out the space you want to caulk. You'll be amazed at what you find there. I have also taken a utility knife and cut off the edge of the seal to form a v to caulk in. This works too. I have had several cars I caulked in this way on the surface. The caulk holds a long time and has the advantage of being out where you can see it if it fails.

anyone know if a sedan windshield can be cut down to be a coupe windshield?

Thanks for that tip, I think I'm going to give that a try with some urethane caulked in. Found it offered at two other places for those interested. Their own site lists them for 112 dollars. These two have them for 90 right now.

This seal appears to be for sedans/wagons according to the manufacturers website. Can anyone confirm? http://www.prp.com/images/Jan2009MoldingGuide.PDF

Any other sources for W123 coupe front windshield seals? Even URO garbage?

Confirming this post, I remember reading another post stating that the coupe windshield seal is no longer available but the sedan seal can be cut down to fit and mated together. Not sure if the side of top would be best.

Regarding sealants, I tried resealing my windshield with RTV from the auto parts store and it did nothing. Then I read a post talking about the Mercedes non hardening sealant. It is more expensive but it is wonderful stuff and solved my leak problem. You slip the nozzle under the rubber gasket and pump it in with a caulking gun. You need to be careful not to put too much pressure on the nozzle though, as it can crack and then you are SOL with a tube of great sealant but no way to get it under the gasket.

in terms of the caulk/sealant - was there ever consensus on what the best stuff to use was? The MBZ brand stuff? I can order that from my dealer perhaps?

I called up the local only glass place that my independent mercedes shop suggested and they said they just don't touch cars like mine, at all unless you are bringing them a new windshield to put in.

my seal has obviously dried over the years and therefore it's pulled away from the glass a bit - but it's not in terrible shape. I used a plastic wedge thing and some compressed air to blast out all the gunk that had settled in there - this was on the advice of an auto glass guy who is friends with my family. I belive it's prepped for the caulk but I'm torn on what exactly to use. I will gladly pay for this mercedes stuff - or is there a similar non mbz product I can find somewhere?

thanks in advance!

There are independent glass people that will/may R&R the glass. Or they will have stuff to seal and know how to apply it. I bought a window for my SD installed for $200. I realize that CD doesn't = SD but just sealing should be less. You want someone that has been working for awhile. The glass people frequent body shops and lower end car lots.

a new OE windshield gasket or any other OE rubber for W123s is at least 25 years old. Even if on the shelf it will deteriorate. I have replaced both front and rear windshield gaskets with aftermarket URO. They fit well and do not leak. It has been 3 years so far.

I think URO quality statements have attained urban legend status. You will find many complaints on the forums but one never hears from the many more like myself who are satisfied. Lets face it, if you want to keep your W123 on the road, you will just have to make aftermarket decisions. Your only other choice is to junk it, a crime for one of these wonderful time machines.

In case anyone is interested, AutoPartsWarehouse and JC Whitney are owned by the same company and parts ship from the same warehouses. Crash parts usually suffice. Branded parts have quality of brands. AC Compressors used to be junk. Fluid containing heat/temp exchangers (ie heater cores/condensers et al are usually acceptable. Most are China Taiwan.

this 3m stuff looks like it might be the right type of sealant to use for those attempting to seal in place (non-hardening, etc). anybody know of anything better?
