Hiya Ben,
Definitely will be adding this new Tamiya kit to my collection - been awhile since I used TS-50 Mica Blue!
Wheels turned out great and just for reference, Tamiya offers another solution on their website for applying the black- scroll to the bottom: http://www.tamiya.com/english/products/24323toyota86/index.htm
Looking forward to seeing more of this build - keep it up!
