Almost as it they were wiping on a very rough surface.
I tried to clean with a lot of wiper fluid... nothing the noise continued.
then the rain intensified and visibility became REALLY bad and to make it worse it was getting dark which made it even worse. It felt like there was a layer of something on the windscreen.
I thought it’s moisture on the inside...
But No! The demister was on and you COULD NOT wipe any moisture or anything on the inside!!!
when I finally went home after my rounds I inspected the windscreen and I felt and saw something rough on the windscreen. the best I can compare it too is if you took hairspray or superglue and it dried down on the glass.
It’s very fine tiny dots so it looks like something that would have been sprayed and it’s quite evenly distributed... can’t figure out what it is!!
the frunk has been repainted... could it be spray of top coat?
I clearly tried the wiper fluid, glass cleaner and coarse microfiber cloth, tar remover but nothing so far!
the SC recommended the above and asked it it was tree sap or dust... clearly not..
If it rains lightly is not that bad, but if it’s heavy rain visibility is reduced significantly (Like 40%)
Next visit to SC booked for end of the month... but here rains constantly (UK) so I cannot Drive around like this!!
I can’t manage to capture what is looks like when the windscreen is dry as you can’t see anything unless you get very close to the glass.
These are the best pics I managed to take...
(The visibility from the inside pic is just when spraying the wipers, when it rains is x20 worse)
Do you know what is could be?
Do you know what else I could try?
