I did the textured- with the stuff that came in the kit. I believe it's enough texture to provide some grip, but gonna be way easier to clean than stuff with rubber in it. I have to get the jeep dirty to test it myself.
And the possibility of eventually using the extra gallon on the sliders and wheel wells is pretty good right now.
