I love the custom roof paint and decals, top notch work. I'll definitely be keeping an eye on this one.
Something about this car just calls out to be painted purple. I built one of these some years back as a tail-dragger. I wasn't following any particular customizer's work, just using some of the bits in the kit.
It's not nearly as nicely done as yours is looking to be but I used a similar paint method, laying down silver first then a purple top coat.
If you want to see it, I think I can drag up a photo and post it.
