I have these retracting running boards on my SUV and it took about 4 times of totally busting my butt before I realized NOT to use Armor-All on them. That does hurt!
Got those on my 2015 F150 4x4 Platinum Model SuperCrew. First truck I've ever owned with the retractable running boards. I got them so it would be easier for my elderly Mom to get in & out of the truck when I take her to the Dr. Or to buy her grocerys.
First time it rained, and I stepped up on the running board in my Croc's, I busted my ASS!
Mine are slicker than goose ShiiTT.
