Would anyone who uses this be willing to chip in with some advice about it?
Mix putty 1:1. Play around with blob until it\'s too hard to take any more manipulation - this is honestly the best way to get used to the working properties of any new epoxy putty.
Mix putty with more hardener, play around again; mix putty with more resin, play around again (MS is very tolerant of large variations in proportions of the two components).
With a standard blend you\'ll find the putty will go through some distinct phases during the curing process:
when it\'s first mixed it\'s clay-like and soft;
then it goes through a firmer phase;
as it continues to cure it becomes less clay-like and a little more plastic, similar to the \'leather hard\' stage in real clay;
final stage, just before it becomes too stiff to really take a mark, is something like a firm wax.
Each phase is ideally suited to doing certain kinds of sculpting - big movements when it\'s soft, first rough shaping; general folds and details when it\'s firmed up a bit; tighter folds or wrinkles when it\'s gone stiffer; sharpest details when it\'s very nearly set and it\'s often best to cut it to final shape at this stage as you get the cleanest cut.
The general working time you\'ll get as well as the time to full hardening will depend on the amount you mix up, how thoroughly you blend, the temperature and your body chemistry. Full cure (for maximum hardness) at room temperature takes at least a full day; I\'ve had it take as long as 48 hours. Heat speeds up the curing time.
This past thread is worth a quick read:

MS is very safe but if you mix any two-part putty with your bare hands you should always wash them afterwards.
This is so that you minimise the chance of getting sensitised to their chemistry.
