I have a red 97 f150. I have this waterspot problem. It rains and al tehses waterspots appear on the hood. I wash, wax, it rains, and waterspots appear. What am i doing wrong?

Second, after i was i get all these little white bumbs on my hood.abotu the size of a grain of sand, just not gritty, or moveable. How do i get those off, and how do i prevent them?

 

After you wash are you drying your truck off? You'll have to dry the truck off.

To remove waterspots then you'll have to use a mild polish to take them off.

You can't really get waterspots from rain since it doesn't have any minerals in it. The spots you see after rain are most probably dirt the rain picked up either in the air or on you paint surface. The rain simply puddled it together and then left it there when it evaporated. They should wash off the next time you wash your truck. If they don't, then you'll need to use a paint cleaner like Pinnacle Paint Cleansing Lotion.
