with the intention of adding the aforementioned detail to models(mainly armour) i purchased a screw punch and tested out the manufacture of scale rivets on the wreak of my mk 4 and parts of other kits it works fine i even have a trick to paint the edges of a whole bunch of tiny disks at once....but one thing that seems to be going wrong is that the little disks are de-lamiating which is anoying a makes them look unsightly is there any way to treat the source matirial(what the disks are cut from) to prevent this? onece on the model a coat of varnish will keep them together but they tend to do it in assembly ...any ideas?
