    Does anyone else find it extermely silly that when you put water on the windshield from, the reservoir the wipers go first then the water sprays? its the only car I've ever had thats done it, Risks scratching the window wth dirt before adding water.

    ^ great design if you’re into selling windscreens... for the rest of us, yes, it is a bad design, simply stupid even :rolleyes:

    VE used to spray under the wiper didn't it. I always thought the VE had a delay when the wipers came on when you pumped water first. In the VF, It does spray water straight away but a lot of the cars have the water tubes empty when it's first primed. One of my cars actually sprays straight away to avoid windscreen wiping without water.

    Yes, VE sprays below the wiper so the leading edge of the wiper is rubbing across dry screen on the first pass.

    I much prefer the older method of the spray nozzles being remote from the wipers so the screen gets wet in front of the wipers leading edge.

    Yes it seems counter intuitive to say the least. Maybe there's a way of factoring in say a 2 second delay on the wipers starting after pulling back on the the stalk?
    @stooge or other techno savvy people?

    How would that get water in front of the leading edge of the blade ?

    VF sprays onto the glass from the cowling under the bonnet. Not from the wiper arm like the VE.

    Anyone else notice the nozzle leaking water after its finished wiping. Only on my passenger side. Pretty sure it's leaking from the nozzle and not left over water.
    There's always something with commodore wipers and washers. My old VX used to drip the water onto your lap after wiping if you had the window down.

    Mine is fine... water comes at an instant on my VF. As soon as I pull the stalk, water comes at the same time as the blades.

    Sometimes it has it's days where it has to pump the water up a little, but majority of the time the water is instantaneous on mine.

    Yeah mine too.
    I really think it's a bit of a non issue. Despite constant dust during these drought years, I've not had a scratched windscreen and my first set of blades lasted +5 years.
    Maybe there's a valid reason for it being dezigned in that way? Safety (not restricting vision with water), ADR conpliance IDK?

    It's news to me. I tug at the bit (enthusiastically, as in yesterday's colossal deluge on the outskirts of Melbourne where the fastest wiper speed was comical rather than effective!) and the water comes out, same as VZ before. Maybe there's an air leak in the line somewhere that causes a delay??

    Winscreens will be damaged far more easily and more commonly by roadblast ('sandblasting'), stone chips and even hoons throwing missiles off bridges. But scratches...that's something I haven't seen...

    I have a few chip marks in my screen which for a car that's not driven much and rarely sees any out of town road use mystifies me.

    It makes me wonder if the new screens are softer than the old ones like the screens on many Euros are.

    As far as scratching goes from the wiper blades, years ago on my VZ I turned on the washer/wipers to clean off some bird poo and I ended up with a light ten inch scratch, I think the poo must have had some grit in it.
    The scratch annoyed the crap out of me from that day on.
    Since then I carry some cleaner and a cloth in the boot to deal with that type of issue.

    I can't say I've ever had the screen scratch from accumulated dust but common sense says it must have some abrasive effect and therefore I prefer to clean my screens manually myself and I always keep the automatic wipers off and an if it's only dust I let the rain well and truly lubricate the screen before I turn them on.

    My thinking is due to having seen many screens with the faint haze mark showing the wiper action and believing it has to do with abrasion.

    It saves me from having to machine polish the windscreen to remove it.

    I'm over fussy I know but the more I can reduce marks on my cars the happier I am.

    ^ yeah, I also suspect the glass composition is not as scratch proof as the glass in previous older cars I’ve owned.

    Heck, there was even a period where some glass had minerals or coating within to help with heat rejection to reduce aircon loads. But that seemed to upset those road toll tags so I guess windscreen glass composition was quietly altered and cars interiors seem to get hotter (it ain’t global warming)...

    The glass in the VF looks of a much higher quality than what was on my VZ! May even be impact resistant, IDK. No stone impact marks, scratches or whatnot. And after 183,000km of trans Australia travel in that VZ, the windscreen was sandblasted (terribly) and had 3 peripheral stone impacts, but not a single scratch anywhere.

    I've noticed light scratches on my windscreen and way they are oriented it seems it was caused by the wipers blades so there is definitely a lack of lubricant when wipers goes off. I live on the coast so I use the wipers almost everyday to clean the glass and yeah It silly how blades goes off before water sprays.
