    Extremely Stubborn Water Stains

    Ok, I got some water stains and I cannot get rid of them! Tried good Car wash 3x, using Meguiar's Soap, then tried Meguiarls Swirl removal, also tried a bit of Vinegar, and now I will try Meguiar Scratch Remover 2.0. But if it does not get removed with the Meguiar Scratch Remover 2.0, would it be any harm if I leave it just as is for few months? I am going to save money to buy all the equiptment to buff it and polish it my self......but man, one year old car, **** load of water stains.....dam apartment sprinklers.....

    Well, with good washing, you should have removed the worst of it, that would keep etching in.

    As far as removing.... hard water can take some effort. Even wax is just a few molecules thick, something strong can get past it.

    To remove swirls, spots, etc, the products do need worked in some. A common mistake is to wipe them on and remove like a polish or wax.

    If they are type 2 water spots that would require more effort. They are stubborn as you well know. I personally would get after them as soon as possible. It is always easier to maintain, then to let them build up for a couple of more months, then try to remove them all.

    Sounds like a case of extremly hard water. I had an '06 WRX recently and I washed it for the first time at my house and it looked like I had given it a limestone bath. Took it to a friends house a town or so over washed it there a few times, waxed it real good and no more spotting. I've since installed a water softining system on the house. and no more spots.

    Yep, water spots can be a hassle. Here in Houston the tap water can get up over 270 ppm TDS and leave spots which are difficult to remove. I've had some mild ones which came off with a claybar and some very tough ones that took #105/cutting pad/rotary to remove. Hopefully yours will be the easier ones!

    If you don't have the time or equipment to tackle the spots right away, it does make sense to keep up your regular wash & wax program. While it probably won't do a lot to remove existing spots, it certainly can't hurt and a good wax job will help prevent new calcium deposits from sticking.

    Good luck and let us know how it comes out
    I saw it on the Internet...it must be true!

    prevent : wipe with QuickDétail , Last touch , ONR
    remove : paint cleaner ( less to most ...)
    DC1 to UC or 105

    try aquagleam filter or something like it .

    Re: Extremely Stubborn Water Stains

    We've seen extreme cases of water spotting caused by reclaimed water used in apartment complex sprinkler systems. When this gets really bad, even rotary buffing with a wool pad and M105 can be challenged. Washing, vinegar, clay, a light paint cleaner by hand - none of these will touch the very worst water spots, unfortunately.

    In absolute worst case scenarios we've seen wet sanding as about the only remedy. The problem with these severe water spots is not that there's something left behind that won't let go, but rather the fact that they are deeply etched into the surface of the paint, so you need to level the paint to remove them. And the worse the water spots, the more aggressive you need to go in order to correct them.

    Thankfully, most of the time they aren't so severe and a little Ultimate Compound via DA takes them out quickly.

    Re: Extremely Stubborn Water Stains

    I know this thread is old but I'm dealing with the exact same issue right now. I have a white Tundra Crewmax that is riddled with water stains (assuming that's what they are. I have a DA but can't apply enough pressure and still keep it spinning so I had to resort to hand application with a MF pad. The Ultimate Compound is doing the trick but it probably takes me at least an hour for a fender or door. The hood took me about 3 hours to prep for NXT. I'll try posting some before and after

    Before shots (you can see where I've done and where I haven't)
