i got these hard waters stains over the summer on my hood. Ive tried clay barring and waxing and nothing will working, i was thinking of getting some rubbing compound but im wondering if its already too late. its been a long time since i got these stains, its not a huge deal since ive got a dent on my hood that ive been wanting to fix, but my fender is perfect. is it too late to fix this?

 

I would try a polish first. Start out with a light abrasive polish and if that doesn't work bump up to something stronger. Depending on how bad the water spots are, it might need buffer with a high speed polisher or it might even need wetsanded. Like I said, try the polish first and see what happens.

 

Polish first then mild compound such as 3M brand. Water spots are usually calcium which is a metal and eats into the clear coat a bit.

 

You sure its hard water and not eh clearcoat lifting? You might want to take it to the dealer in case it's covered. Good luck.
