The world-famous epoxy putty that sets rock hard and can be sanded and machined when set. It can be manipulated like putty and cures rock hard in 2-3 hours. Very useful for many areas of modelling, moulding and filling. Use it also in miniature modelling for making small components that you can carve to shape whilst retaining detail perfectly. It even sets under water! Available in different colours to suit the scenario of your choice.
