I have never been a real fan of the white 4X4 notes on the mud flaps, but really did not want to cut them off, so . . . .
I was doing the wheel wells with some stuff from Griots and decided to do the mud flaps then the rear diff and frames in back (first nice non-snow on the ground day in a while) when I noticed that the cleaner was taking off the white marking; it is not molded ion, it is applied.
The picture shows the result after a first cut so it is not totally cleaned up yet, but I like it better.
