When you are done removing hard water spots with your system can you still see very light spots in the direct sun? Or can you see spot shadows on the glass when you fog it with your breath? If either than you have not removed enough glass. Cerium will only take you down just so far. It is good for light polishing of light spots. But when the spots are very heavy you must use a grinding process. Then clear with cerium. I would like to start this discussion without mentioning any kits. NO KITS. Lets talk machines, pad materials, polishing powders, micron range, rpms, fpms, surface quality, transitioning, etc. Lets talk about the science of hard water spot removal. I think we have come to a time when this is possible.
