I've only ever used the the blue stuff but now they make this orange stuff that is supposed to protect to -30 degrees (not that it ever gets that cold here...). <br /><br />I needed to refill the washer fluid today and the store only had the orange stuff.<br /><br />What's the difference? It had a lot of chemicals listed on the bottle ... will any of this stuff hurt the paint?<br /><br />Also, they sell some other kind of fluid that is supposed to repel water off of the windshield. Does it work? I like RainX, but it seams to wear out quickly. Maybe this is a better way to make it last longer.
