Thanks for the info... I will give it a go!A clay bar is safe, just be sure to follow the instructions for use. Usually they come with a spray bottle filled with a solution (kind of like watered down dish-soap). You spray a little solution on, and gently run the bar across the area.
I'll be doing my whole car next weekend more than likely. It's been needing a nice deep cleaning and exterior detail.
There is a metal flake like particles that are stuck on the surface...the lipstick **** came off.wash the area with soap and water to remove the road dirt-then pat it dry so not to smere the lip stick-then on a clean soft rag or old towel spray wd40 on it and wipe it off. lip stick believe it or not is made from animal fat and some have cow poop in it and wax- true fact!!! wd40 will break it down then just wash the wd off with soap and water.
