Rivets - Archer transfer surface details - Have read about these, as used in the Railroad Model Craftsmen magazine July 2009 article on scratchbuilding tankers. Looking forward to trying them out without going too overboard and counting ;-)
Silicone for moulding - Highly recommend UltraSil, from ModelCrafts and Hobbies for example
Resin for casting - Highly recommend ProCast from ModelCrafts and Hobbies for example, is slightly slower setting but stronger compared to quicker setting Easycast. Gives slightly more time for filling moulds!
Whatever is lying about !
