I have the 2010 Husky Liner Originals. The new design comes over the door sill. I love them so far and would highly recommend. They are not slippery at all. The instructions that came with them say to clean with 409 or simple green. I would imagine if you used armor-all, then they would be slippery as hell, but i just use 409, they look great, and don't slip at all.
