Fantastic. I plan on pouring some heads this weekend. Any chance you could stick a couple different plastics on those heads so we can see a finished product? Thanks. As always, just fantastic.
Here ya go McGoo....

I added another color head I do the same way with different colored paint and components. Its at the top of the pile and I call it Almost Blue. I use this color more than any other hands down. And I use it with every color of plastic imaginable with the same degree of confidence and success. The combination of paint and other components makes this head look blue in one light or angle and purple as purple can get just by turning the head in the light. Its sort of like a changable plastic color.
I'll stress here that the Raspberry is definitely not a pink when its in your hand, either stand alone from the bottle or after it's been doctored up. The Hot Pink body on that 1/16 head really pulls pink into the head color. In reality its a purple, but then its not really purple either. I've begun to dabble with the Raspberry as a swing or transitional color from purples that I like so well. The 1/32 head with the small white plastic on it shows the almost purple under tones real nice.
For those that paint their own toys, the Candy colors of powder paint are just flat out cool. Because they are transparent, its best to use them on fresh, shiney castings for a true Candy colored coat. If you are going to blend glitter, I suggest using glitter in the .002 to .004 size range. The smallest I use is .004. I get mine in two ounce bottles at Hobby Lobby. Its a polyester glitter and holds up to the heat required for powder painting real well. I've tried the .008 glitter used in plastics but that size tends to be the beginning end of graininess in texture on the head so I stick with the .004 and my small heads come out great.
If any of you feel adventuresome, try pearls or hi lites in some colors. Black, dark blue, dark purple really take on some weird hazing that ends up one-of-a-kind beautiful. The candy or transparent paints display the hi lites pretty much like your plastics will, but the degree of light reflection and refraction is amplified because of the shiney base.
More and more people are reaching across the lines of plastic injection into lead casting/finishing and vice-versa. So many of these components pull double duty that I thought a topic along these lines woiuld help to ignite some fires. Fun stuff guyss if you take time to play with it.
