If the Claybar + cleaner wax + swirlx combo was not able to get rid of the watermark, it can be due to one or both of the following:
- The watermark is etched on your paint. Check the watermark closely... try to feel it with your fingertips. If it ain't raised above the paint, it's already etched into the paint. This is usually caused by acid rain that was allowed to dry under the sun. If the watermark is etched, then yes, you'll need something more aggressive than SwirlX. ScratchX may do the job, if you're working by hand.
- Sobrang nag-tutong na yung watermark. Calcified water. Nasty. But not as bad as etched watermarks. Try a water+white vinegar solution (sorry... I don't remember the dilution ratio...). If it works, make sure to wash and re-wax the treated surface.
