Dan asked: How do I remove stains from a factory sealcoat on my car? I have water alkalie spots on the factory sealant of my Mazada Millenia S, and I can’t get them out.
Acid rain leaves marks and etching on the surface that appear to be under the sealcoat. In some cases these spots can be buffed out, but it is often just a temporary fix. The stains will often need to be wet-sanded to be removed completely. For a permanent solution, it is necessary to apply a new sealcoat or repaint the car.
In some cases, the damage will be covered under warranty. Check with your dealer to find out if the warranty covers a new paint job or other solutions to remove the stains.
