windscreen sealing - what first ?

Post by Propshaft » Wed Nov 23, 2016 1:11 am

Just Managed to mount the new heated windscreen.

Now comes the sealing: what first?
First the seal compound and afterwards the chrome filler?
Or First the chrome filler and then the sealing?

Happy to receive advices ......

Cheers!
Michael

It depends which model.

Se5/5a (and I presume coupe too?) is rubber onto car first, then glass into seal and filler strip in last. 6 series etc is rubber onto glass, then put the whole lot in, chrome strip on last.

sorry, it´s a SE 5a.

I do mean the sealing compound, not the seal itself.

First the rubber, then the glass.
But then first the strip, then the sealing compound? Or the other way around?

cheers!

The only sealing that should be needed is a small amount around the edges of the screen itself to seal in the heated elements - this is just to stop any moisture getting into the laminated section which holds the elements themselves.

There's no need to seal the chrome filler. I always use sealant around the screen aperture before fitting the rubber seal and as Phil says, the edges of a heated screen should be sealed (a specific two part sealant is recommended I believe?)

Evening chaps,
I watched the guy who fitted a new windscreen in my 5a a few weeks ago and yes, procedure he used was as stated above. The only thing slightly different is that the he put some sealant between the seal and screen just as "belts and braces" against potential leakage.
I was amazed at how much the chrome filler strip spread the seal and made it fit really snug into the body aperture!

Same here I had Autoglass fit mine into the Coupe. They have an electric motor powered goo gun so can maintain an even trail of the stuff. Rubber went into the body aperture then glass into the rubber as previously mentioned. Then sealant injected into both sides of the rubber seal. Then the chrome locking strip. The goo comes out massively and is then scraped off with a spatula.

Thanks, guys!
I will follow the Autoglas procedure.
My goo gun is air pressurized, and I will warm up the goo on my room heating.

Pictures will follow as I have put some underlay at the bottom of the aperture between rubber and body to lift the screen.

cheers!
Michael
