been a while since i've gotten on here but i have a rotary and i guess i used a little too much product and got some sling (little white dots) on different areas of the truck. How do i get this off? I have already waxed the truck but i know clay bar will work but is there a better way without stripping all the wax off. Also it is in the wiper cowl too and i have scrubbed and it won't come off. Also am i using too much product when it slings?
