i ust wanted to share something i found totally neat, i found the tamiya fast curing putty to be completely awesome! not only does it dry in 1 min under sunlight but just for 2 min under flourescent light! really cool for someone who is as lazy and impatient as me ; ) and as for the epoxy modelling clay aqua.. just mix it up, kneading it for some time till it turns white and voila, instant modeling clay that hardens like rock in minutes.. really great for scratch builing :)
