Now worries Smarty... my add on for greenstuff.
It is extremely STICKY to work with. You have to keep you figures and tools wet to be able to keep this from sticking to your hands. Its also exceptionally difficult to remove (or prevent) fingerprints.
However, I've stopped using sculpy when I need to add something on to a piece "permenantly" I'll still use sculpy if I'm going to a make a mold of it but if its a permenant addition I'm going with greenstuff.
I also use greenstuff to bond some pieces together. For example, in my Diva figure, I've used greenstuff to creat the next and bond together with a ball joint for the head. I also used greenstuff to bond the Orn Free Ta head on the body.
The other downside to greenstuff is the cost. Its about $10 at Gamesworkshop. You don't get very much (but it goes a long way if you are only using small parts). You can get a lot more sculpy for the same money.
I also asked some questions about greenstuff a few months ago - [http://www.jedidefender.com/yabbse/index.php?topic=11442.0] Here's a Link[/url]
