Car is now resanded with 80 grit, and any imperfections are addressed with fiber and filler as needed. All exposed metal’s being prepped with Debeer Washprimer, which is sprayed directly to metal, and sanded again with 120 and 240 so it will take a couple of layers. The fantastic news is that there’s no rot (other than rear valence which is replaced with new) or any evidence of the car being in an accident - soooo glad the history of the car checks out, to paraphrase the old saying “the proof is in the pudding i.e. metal” :cool:

While I’ve attention, does anyone have any thoughts or recommendations which glue to use to stick the windscreen back on? The reason I ask is because the original glue was still somewhat soft, sort of caulk like, and the adhesives available today usually cure to rock solid which may not be a good fit for a 40 year old convertible.

The options are a modern PU or butyl rope with the integrated heating wire.

I couldn't find any fitters who would do the job with a butyl rope so had to go with a modern PU.

The advantages of using the butyl rope are the ease with which the screen can be removed without paint damage.

Anyway if you go with PU you need to watch the fitter like a hawk to ensure the do not smear any excess onto the trim clips or beyond the screen which could then impede the trim.

After mine was fitted I still did have to immediately go round the screen and clean off some excess in a couple of areas on clean out one of the trim clips which got smeared.

Doing it again I think I would go for the butyl rope and do it myself.

Dont forget to get the correct spacers to be used ahead of fitting as the fitter probably wont have the correct ones or know that they are needed at all.

@RaceDiagnostics Thanks a bunch Jim, as always, Jim! And as always I have more questions: 1, are the spacers available from MB? I didn't see them in EPC in the windscreen diagram. 2, when you say butyl rope with wire - is this what you have in mind? Butyl Round Cord 8 mm x 6 m Black: Amazon.co.uk: DIY & Tools I'm open to either option as I'll probably refit the existing windscreen, and if the unspeakable happens I'll get a new MB sorted through insurance - right now the dealer is having a hard time figuring out which p/n is the correct for my old lady, A107671110 or A1076710210.

Thanks Jim, perfect. I think the butyl kit A1266700193 might not be available any more, in which case I'm stuck with aftermarket alternative or PU. I'll call up to a local Mr Windscreen, he's been around for decades and might have some pointers. I'll have to make up those plastic spacers too.

It will be interesting to hear what your old timer windscreen fitter has to say. As for the butyl part number, I guess it must have changed but I am sure there is one still available as most of the guys in Germany still go for this option rather than PU.

Thanks Jim, right you are - the kit was superseded by A0006700293, which I just bought in the US - at $62 seems like a no brainer as it does sound like the cleanest way to fit a windscreen.

Are you sure you want to refit an old screen onto a "new"car? Old screens usually have lots of little pits and scratches.

Yes @cushjbc , no problem - I will follow the instructions Jim shared.

@Aussiemerc - I'd rather a new screen of course, for the time being the challenge is that I don't know which is the correct p/n for my baby and MB dealership are struggling to confirm that. Aftermarket is a tough option as private deliveries are a challenge to Ireland, waiting to hear back from Classic Autoglas - Wir haben die Scheibe., and organizing via one of them windscreen replacement companies is likely to be a struggle too.

Thanks Jim! I didn't think about SLS, but you're right - it's available. As a side note 10 mins ago I got a box from SLS with €1k worth of weather seals as all existing ones were shot.

Jim, or anybody else who replaced weather seals - I assume yours also arrived covered in baby powder look alike? Did you clean them etc. or fitted them as is? The ones in the box are aftermarket, but a bunch of others thay came from MB are the same so perhaps it's the intedned factory look and feel?

Mine looked like that. I cleaned the non glue sides with Wurth rubber protector. Cleaning the slits where they have to slide on doesn't hurt also as it helps the slide on progress.Having said all that I don't think that powder is bad, it just looks poor. Wurth makes them nice and black.

Same here, recently replaced most of my seals and they were powdery white too. Same as Aussiemerc, Wurth Rubber Care does a great job of cleaning the rubber, making them a rich black and helps keep the rubber supple. I did this after the seals went in
