Porsche Macan Forums

Autoglym Fast Wax works great after washing - don't use near windscreen wipers though.

It's not really after washing, although I can see it until dry.
For instance the Macan has been detailed and garaged. I open the garage door and humidity hits the car. For some reason the windows seem to attract moisture and show this horrible finish. Once cleaned with IPA (not India Pale Ale) I will try some wax to see if this helps as the body after DoDo Juice doesn't attract the moisture.
I will try to take a photo to see if it shows the issue.

That’s correct Paul, the old grey cells are still functioning!

I had something similar in the back of my head from somewhere but as I couldn't quite remember where so said nothing, it might have been part of the information on SWMBOs Audi TT

I wouldn't use wax on any of the glass, especially the windscreen. I'm not a fan of any aftermarket coatings on glass at all. Some may show a benefit initially but after some wear and tear produce some dreadful effects which are very difficult to correct. This may be the reason you have these issues now.

You say that all of the glass is affected. Only the front side windows have factory hydrophobic coating, so this isn't the issue. If the car has been like this from new, or at least as supplied by your OPC, then I would get them to investigate and repair. They would very likely get a professional detailer or glass specialist to do the job, which I think would be the best course of action now particularly as the issue may get worse over time.
