To duplicate that "under lights at night" effect, I turn out the other lights in the shop and use a high-wattage incandescent light (regular, old-fashioned light bulb, just a strong one). By varying the light's position and my viewing angle, I can find a combo that shows all the flaws. It's the only way I can spot light marring on silver and it works on other colors too.
reeksti- There are a lot of threads on how to use the PC, the general rule is to move it slowly so it has time to do its work. I polish at speed 6 and I do not work my polishes so long that they dry.
If the orange pad doesn't do it, get a 4" pad setup, that allows the PC to work far more aggressively.
And consider getting a foamgun and working on sciencing out your wash technique. Since I got really careful (and thoughtful
) about how I wash I hardly *ever* have to polish out marring.
