After building Tom in 2014 I felt that I could tackle Crow in 2015. With Crow I was lucky enough to get a handful of parts from Ebay but I still relied on MST3Kbots for the harder to find components like the shoulders and bowling pin beak. I have not added electronics to Crow yet. His design doesn't lend itself very well to hiding components.
Crow's paint is even more difficult than Tom. It's a two stage process with a shiny gold base and a lime gold metallic candy coat. Too many candy coats and you'll end up with a too dark, incorrect tint. There's also a flat black used for all "inner" pieces.
The first step is to get every part coated with the gold base. When you do the lime gold metallic coat you want to hit all the parts with the same number of coats at roughly the same time. Temperature, humidity, and flash times all contribute to the color fastness.
You can see how much of a difference the candy coats can make.
