I'm trying to remove water spots from my car >.< Any solution?

In fact.. anything I can do to the car to avoid water spots? car is parked unsheltered every night >.<

So can I make this conclusion:

If I have no covered car park, then getting rid of waterspots in Malaysia is a waste of time? Because almost every morning my car is covered in dew. Almost every other day it rains. I cannot afford to dry my car every time it's wet. I simply don't have the time. I'm guessing from your replies that there is not product that can protect from water spots. The only protection is shelter or constant drying.

But if it rains every odd day, and there's dew on my car every day, it means I need to dry my car every day, and worse, if dust have settled during the day, and dew settles on the dust during the night hours, it would mean I cannot simply dry my car in the morning, as I may end up scratching the paint. So... besides a daily car wash... how can I avoid water spots? I have no sheltered parking. I guess... Nothing can be done but to accept it? I currently wash (and immediately dry) my car more than twice a week. But there are already water spots everywhere, and they won't go away.

I'm tempted to try vinegar, but afraid I may ruin the paint or other parts of the car. Is it safe?

KC, any guide to how to use ONR in Malaysian weather? Like... what is your actual dilution ratio? US or imperial gallons? Do you rinse first before you use ONR?
