I have the following questions in regard to removing hard water spots.
The vehicle I am dealing with is a black 1995 Corvette. My customer purchased the vehicle used about 6 or 7 years ago and it has had a problem with water spots ever since. The spots are mostly on the hood and they appear to be below the surface; as you cannot feel them with your fingernail. The windshield also has a water spotting problem.
1- What are some of the safest ways to remove calcium water spots?
2- Are there any products available to simply dissolve the calcium buildup?
3- Can the process be done by hand? Thus reducing the chance to damage the clear coat.
4- Would you consider using abrasive products in an attempt go below the surface to remove the spots?
5- Would you recommend having this car repainted?
6- Can water spotting appear to get worse with time?
7- Can some last step products actually highlight this condition and make it look worse?
Thanks in advance for all replies.
