The re-designed Enterprise for STTMP was one of the most if not "the most" complex paint skemes I've know of made for film.I found a web page on the guy who was commissioned to paint the model back in 1977/78.It took him 18 months to paint it.6 months of it was a repair job because the Enterprise got an electrical fire and they had to rebuild and repaint one side of it.From what I researched/read, he used three primary colors.Red,blue green and the others were white,gold,silver and black.These were all pearlescent, transparent lacquers(no longer made due to EPA restrictions). Basically the Enterprise was sprayed a base white,and all the other colors(pearl white, red,blue,green,gold and silver) were custom mixed in small quantaties for the many varrient pannel colors.The idea was to keep the paints and colors transparent so they would refract off of one another,one color would meld to another and thus produce the illusion that the paint skemes would change before your eyes due to angle and light source,like an abalone shell or a pearl.The paint finish was so bright(as I;m sure allot of you know this info),they culdn't film the Enterprise with traditional blue screen,the mattes had "holes" in them do to the paint finish.They dulled it down with talc,lower lighting and produced the mattes with the black velvet background.Paiting the PL re-fit like this is a daunting task.I had searched and searched for the right kind of paint and I just can't find the irridescent/parlescent paints.They don't have the same properties.I've researched urethane paints,enamels and acrylics.I found a group of acrylic inks,but they cannot be airbrushed, theacrylic paints fall short as do the enamels.The difficult part is being able to thin the paints down enough to closely work on the model's surface with low psi and little to no overspray unless you just love masking.The pearl urethanes are really expensive($500-$900 per quart) and I've little experience working with urethanes.They are a bit intimidating.I've come to the idea/notion that a compromise be met and that custome mixing the paint's is a necessity. I found some automotive enamels by House of color and found all the necessary/primary colors.They are special formulated and are made "thin".I think that eye-balling the the mix of paint to clear coat to get the transluscent properties from the paint is obtainable and then adding the recomended ammount of pearlescent powder will make for astounding results similar to the actual miniature.The other thing I think is necessary is the use of a double action airbrush,virtually every pannel is of a differnt hue and twaek off the other color.Pearlesent white, white/blues,greys,silver,gold,greens and purple of varrying intensities .It be a hell of a challenge even on a 350 scale model,but I think well worth it and rewarding.
