You all should reply in the comments of the video too! I will add some of the best ones on here :)
In regards to slippery when wet, rough sand it (tip in the video!), or cut some ridges in it, or rough it up with a knife, etc.
And as for the foot pad application, alternate with regular/old piece of padding.
Yeah, rough sanding doesn't work. The material is just so slippery. Awesomely grippy when dry. No go when wet. Cutting grooves doesn't work either, as they still don't give much extra grip and it compromises the strength and durability of the rubber.
I have wrapped old mountain bike tubes on my steel roof racks for (slightly) improved grip and reduced damage to anything that gets throw up on top (boards not in bags, timber, aluminium etc etc).
