Teflon Tape Around a 993 Windscreen

[Glassman]

Teflon, or 'helicopter' tape is used allegedly to negate the noise of a creaking 993 windscreen (sometimes used on 996 models too).

It serves no purpose other than to trap water and potentially harbour a damp and moist environment for a nest of tin worms to thrive in.



Snake oil.

I've removed and refitted countless creaking 993 windscreens, mostly to investigate a creaking noise. Most have had Teflon tape on them. Get rid.



If you want a creak-free 993 windscreen, have it fitted properly.

You're the chap who used a building grade "low modulus, non corrosive, silicone neutral" 'special sealant' from Travis Perkins to 'seal' your front windscreen, right?

Oh how we laughed.

If you mean did I follow Porsche TSB 9501, and substitute a Dow Corning 791 (i.e. modern sealant designed for glazing/metal applications) for the Bostik 6050, then yes

Thanks to the TSB 9501, there is now nowhere for water to sit in the lower windscreen corners against the metal and trapped under the trim.

HTH

Here is the link to Porsche's TSB 9501 again, in case anyone missed it.

...and I'll say again, there are much better - far more suitable - automotive grade products available for the job.

Getting back to the subject matter, TSB 9501 mentions nothing of Teflon tape.

I've just had the windscreen out to repair the start of tin word so would be interested to know more. Obviously the area on mine is nice and dry at the moment so would be an ideal time to fill the gap. I did a search for the Bostik 6050 but didn't find a lot, does anyone know where to get hold of this sealant or an equivilent, apart from B & Q !!
Thanks

Where are you/the car based?

following the TSB helps to reduce the creaking

A correctly fitted screen will not creak.
