Contour Enthusiasts Group Archives Forums General Troubleshooting My paint won't come clean!

I have hard water stains on my hood that won't come out. The person who owned my tour before me never waxed the danm thing. She parked it in a car port and water condensation would drip on it every mourning. I tried mothers clay bar and 3 step polish. I even tried turtle wax rubbing compound, a bad idea yhat didn't work. Does anyone have any suggestions(other than new paint), maybe a color matched wax ? .
