Just notice these spot all over the car, especially on the hood. How to remove them? Wet sanding? Polish? I tried clay, and cleaner wax with no luck.

 

hard to tell from the pictures, but that's not clearcoat peeling is it?

If not, then my guess is hard water spots--caused either by dirty rain or high-mineral water that you used to wash it--hardening on the surface. Depending on how long it sat, it can cause damage to the paint. I'm sure there are high-dollar products to take care of this, but you can actually use distilled vinegar to take care of it to. My friend that does detailing calls it a "mild acid bath" or something, but realy he's just putting distilled vinegar on a sponge and rubbing it in. Wash your car first, then use the distilled vinegar and let it sit for a minute or two before rinsing it off. Do individual panels at a time. Understand that this also removes any wax or polish, so when you are done you will need to apply wax again.

 

def looks like water spots. some are pain in the *** to get off

 

yeah hard water spots. I got some on my roof.

 

Thanks guys. Guess I better start using the water in the back yard of my house(filter, soften) than the water in the front yard. Time to go home depot to get a long hose.
