Yes the cardboard is included. On the fibreglass housing pieces remember you don't need to sand the scratches and nicks out, the matt clear will go into them and they will largely disappear, the sanding is to provide the clear a surface to adhere to. If you sand into the surface too much it will likely expose the fibres a lot more and they will be standing up out of the clear making for a rough surface that would require another scuff to knock them down and re-clear.
