There are a few other very good quality bed liner type materials that are DIY friendly. Usually for no more than $200 total you get enough product and related materials for more square footage than lower rocker panels.
$800-900 cost is a lot of labor--DIY eliminates that for the most part.
I've been intrigued but never used a product called MonstaLiner:
