Just wondering how folks are treating the top spoiler and top of windshield on the A3. Is it glass? Is it fiberglass? Do we use wax on it?

thanks in advance..

 

Are you talking about the black Open Sky? I think it's made of plastic. So far I've just been washing and drying it.

 

Yes I do have open Sky. Sorry

 

The open sky starting from the front is glass, glass, glass and the last part is black painted steel. The side trims which typically pop out when left in the sun (at least mine do) are made of plastic.

 

And water will bead up and run right off. Unlike the windshield, which needs to be Rain-Xed every month or so because it wears off due to wiper action and ablation (look it up), the Open Sky only needs Rain-X every year or so.

 

I was the whole top of the car and I have open sky, no problems so far haha

 

fusionX, you wax the glass on top???

 

I also wax the glass on top, like fusionX Why not, no harm.

 

I just assumed to use car wax on painted areas only . is it effective on glass the way it is on paint? i just use rain-x on all glass. and its amazing.

 

The dilemma, which is the reason for your post, the open sky is 3/4 glass, 1/4 painted metal . . .

I don't think it matters which you do, rain-x or wax. To me waxing is easier, one less product to buy
