once opened, can you close up a jar of devcon 10112 again or is it a 'goner'. ie. the smallest jar I can find is 500g, but I'm only doing a small recoil lug job and will probably only need a fraction of it.
also, can I use a brown dye on/in it, or does it have to be used in it's original colour?
thanks for the help from any forum devcon users
