Jake I'm assuming your bedding technique can be assembled and disassembled at will? Its just to fill all of the little voids to get a more appropriate fit?
Yes - completely removable and it makes an INCREDIBLE difference in the stiffness of the platform.
5200 remover works great when you can get it to the 5200. If the beam socket is 15" wide, you'll never get the remover into the center even using needles and anything else you can think of. I've witnessed it and seen the ripped deck.
