Best Cleaner for "Grit" on Car Body ?
As I wash the lower panels of my 2000 JGC, I can feel what I can best describe as "grit" on the car finish. It is not visible to the eye, but when I rub my hand over it, the feeling is a bit like coarse sandpaper. I suspect it might be road tar, but I really don't know what it is. I have found this only on the very lower panels of the car, and most pronounced on the very lowest panels just rear of the rear wheels. I believe these panels are plastic. These rough "bumps" will not come off with regular car wash liquids used full strength and applied with a non-abrasive washing pad. Any recommendations on what product I might use to remove this grit?? Thanks !! --James-- |

Road tar would be black...pretty easy to see unless your paint is also black. Tar will usually come off with a bit of WD-40 or a bit of automobile finish cleaner. > > I have found this only on the very lower panels of the car, and most > pronounced on the very lowest panels just rear of the rear wheels.

Make sure it is foreign matter. Clean it good, then try one of the pre-cleaners to be used before waxing. Doubt if claying plastic would work... You might want to have a local detail shop check it for you to make sure it isn't just a rough finish. |

I disagree with another poster's comment about a clay bar - it should work fine on plastic.
