What about covering standard dash with 3M cf eg di noc .There are pics of e36 console covered with di noc on a recent thread . cannot remember who posted !!
Depends on how much stuff is still on it I guess, but I have a spare e46 that still has the metal strengthener and some air vents and ducts in it and it weights about 6 or 7kg if I have to take a guess (I can lift it with one hand so it can't be that heavy).
