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 !!

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.

Could be roughness in the plastic itself?

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.

3M General Purpose Adhesive Cleaner, also marketed as Bug and Tar Remover. Available in any auto body/ paint supply. _Excellent_ stuff - it will remove the wax, so plan on rewaxing immediately. Wear rubber gloves to keep it off your skin.

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

A new paint job after stripping off the 'rubber' anti chip undercoating?
