For the section of the car that looks slightly purple I studdied the reference images and decided that i wanted wanted to get a “sugary” looking effect.
To do this I decided to top the silicone with milti coloured micro beads. I actually used nail caviar in a few different shades of pink and purple in order to get a shimmery multi tonal effect when photographed but without looking like a harsh obvious line.
I added the microbeads using a salt shaker straight after the silicone so it would stick to it without needing to add more glue, in retrospect this didnt work as well as i hoped and i was shedding beads all over the place, thankfully i had put enough on so that it didnt look patchy in the areas that the beads had brushed off of.
I used an A4 sheet of funfoam as a template for the edges so that even if it did stick to the silicone it would be easy to peel off
