We put 3M Shutz or other type coating on nearly every running board. Prevents scratching, not near as slippery, and looks good if just on the step area with the rest of the board body color. You can see some examples at http;//s32.photobucket.com/albums/d41/coilover/
The blue GMC has been that way for 30 years and if you scroll down page 2 to picture 018 there is a 54, and scroll down page 3 to dans49005 for another view.
