I used Hotshot as my base and removed all of his flame paint apps. He was then sprayed with red and then I hand painted (so damn aggravating) the white stripe.

His head is a copied Drift face made of super sculpty rubber placed inside a Smokescreen Kreon helmet. I gave him various other details and ended up using to shades of red on him, a darker red for the exterior auto mode, then I matched the factory red to liven him up in bot mode.
