If you have rock nixes, look for any barbs. The clay bar will remove the barbs, but you need to treat each barb separately and remove it from the clay immediately after lifting.
Small barbs should just roll into the clay and not cause problems. But once you get to a certain size, it might not roll all the way into the clay, and then you have a clay bar with metal sticking out....wiping back and forth across the car!
One last question on this - since this is safe for paint (if done properly) is it also okay to use on the windshield? I have to think that there is more gunk built up on the glass that there would be on the horizontal paint surfaces. Give me thoughts or direction...
