How to safely remove rust stains from Corvette Clearcoat w/o damaging Clearcoat?
While in storage for winter, some rusty water dripped on and penetrated my cover. When cover removed there are rust stains that dried on surface of paint. They do not simply wash off with soap/water and rubbing with usual soft washing mitt. I am sure this is not an unusual type of surface stain for autos. What is the well-accepted product or technique for removing the rust stain w/o scratching or damaging the clearcoat?
