825i floor boards

Hello all. I have just purchased my first 825i. i quickly realized i need two improvements.
1. bedliner or mat in bed.
2. some kind of slip resistant material for the floor boards.

I am thinking about spraying the bed and floor boards with spray in bed liner or the herculiner. Any thoughts. has anyone every put this on their floor boards?

I know i can buy the horse mat for the bed but that doesn't solve my floor board issues. They are really slick when wet or when your shoes have mud or are wet.

Thanks for the help!
