I saw a warning on the suction cups of a radar detector that said some cars have a coating on the interior glass that can be ruined if suction cups are applied to it.

I am not referring to it not working well but referring to the fact that something intrinsic to the interior of the windshiled glass would be ruined.

Does anyone know if Porsche has this "coating" or has anyone had a problem by using suction cups on their front windshield ?

 

Who posted this warning..............the cops??

 

 

I am mounting my PBox on the interior windshield using the suction cups. No problem at all.

 

I used a radar detector held in place on the interior windshield with suction cups on my 2008 TT - for a couple of years and never had any issues...

 

I am pretty sure there were some older P-Cars that had an anti-lacerative coating on the inside of the windshield and it probably refers to those cars.

 

Kind of off topic, but the manual does state that there is a "hydrophobic" coating on the door windows which prevents soiling. "This coating is subject to natural wear and can be renewed."
Any idea what the heck they're talking about?

 

Does not apply to Porsche windshields.

 

Understood. That wasn't my question though. Anyone know what this 'layer' is that is applied to the door windows?

 

Hydrophobic essentially means it repels moisture.
It's like the stuff they apply to the glass on the iPhone. It keeps moist soil (like body oil) from embedding or sticking to the glass so easily.

 

Thanks ruf t. I'm just wondering what material they use for this layer. I had to reach far back, but I remember the definition of 'hydrophobic' from high school chemistry

 

good look

 

For that, you will have to ask Porsche as there are many hydrophobic compounds.

Oh, and as I was thinking about this I realized I was wrong to use the iPhone as an example as it uses an oleophobic (oil repellent) screen, not a hydrophobic screen.
