I played around with more methods of applying the iridescent film and haven't found an easy way to get good results.
The best method I've found is also the most difficult...
Shown here is Bare Metal Foil applied to the brass with the iridescent film held in place with Future Floor Wax.
The big problem is in cutting the film between each facet. Even using a brand new blade and being extremely careful, the film tends to come off the foil. I ended up brushing Future on several times to keep the film squares from falling off and then a final coat whan everything was assembled.
Using transparent two-sided tape is easier and more durable but standard Scotch two-sided isn't as convincing. Small amounts of air get trapped underneath the film vs the seamless effect you get with Future.
I know there are higher quality two-sided tapes available but didn't have any to experiment with.
Doing instructions for this set is going to be a nightmare. There are 30 resin parts, 131 etch parts plus the film MMS lenses and film for the disco ball.
I'm thinking I might provide color pictures of the unpainted assembled kit with some accompanying drawings and dimensions. Doing detailed drawings for each part would be a huge task.
I was (am?) considering dividing the parts up and releasing both an exterior set first and a full interior set later.
Due to the lack of attention this thread seems to be getting (and how few MMS sets I've previously sold) I'm more inclined to just release what is finished at this point and call it a day.
The full set will include everything including the MMS. Those who have already purchased the MMS will be able to purchase the set, minus the MMS cost.
