Milliput

Milliput is a great product.   But it takes a while to get used to it and be able to work with it.  What kind of details are you hoping to re-create?  I use it a lot to sculpt figures (or parts of figures) and for my work on patterns, for the curvy areas such as mudguards, bonnets,..  Also great for filling in gaps if the material or parts under it are strong and won't flex as Milliput does not melt the plastic (like normal putties) and therefore the 'plug' remains fragile, despite Milliput being hard as rock...

After watching a DVD of Jef Verswyvel of Black Box using it, I wanted to do the same.  He uses it for almost all details in a cockpit.  Granted this is for a master, from what I understand, it can be used the same way in an existing pit or wheel well.
