Thank you for the info!HRP said:Before applying a sealant (Zaino), I Dawn wash and then rinse and then use white vinegar. I have used white vinegar (generic grocery store brand) right out of the gallon jug, poured and spread (with a clean cotton rag) once or twice a year on my '77 Black Excalibur (clearcoat), '85 VW gun metal Quantum Syncho (clearcoat), '91 red Buick Reatta (clearcoat), and '02 Silver Lexus LS430 (clearcoat). I then rinse with plenty of water (within a couple of minutes). This will remove water spots, wax, etc. that the Dawn missed. And I'm often accused of having a brand new car since the Excalibur and the Reatta are not frequently seen (11 Excalibur Roadsters made in '77 and only 260 Reatta Convertibles sold in '91. (and less than 600 VW Quantum Synchro's sold in '85).
Comment: I believe that the "fragility" of automobile paint and clearcoat is overstated. Think about all the air born polutants, acid rain, road tar and film, salts, window cleaners, bird crap, insect juices, tree sap, etc. automobile paint is exposed to daily; not to mention all the really horrible stuff you read about on Autopia that the uninitiated use on their cars (which professional detailers revel in correcting). And vinegar certainly would not be as rough on clear coat as a PC with polish. So, yeah, use the vinegar (straight, like I drink my sour mash sippin' whiskey), just don't let it stand too long and then rinse well. You will need to apply a sealant or wax after using vinegar.

White vinegar may remove surface water spots but will do nothing for a paint surface with etched water spots
