In the way of paint though, I added a couple of things, namely a silver faceplate to break up the white, black grills on the front of the car, silver headlights, silver exhaust pipes, and a little bit of silver on his chest.



UPDATE:
To start, I painted the vents on the interior of his shoulder panels black.

Then I added some black and silver to the arm panels.

And finally some black and silver on his hip panels.


The silver on the arms and hip panels give his alt mode silver runners.

On a side note, as much as I can dig a little dude that turns in to a vehicle AND a weapon, that targetmaster (or maybe not, considering he turns into a giant claw) is kinda shoddy, nix that, really shoddy. The vehicle mode looks alright, the weapon mode is ok, kinda, and that robot mode needs a decent amount of paint apps to even look okay.
Instead, I found an alternative, a fourth mode of a little dog bot with a giant maw:

Howling at the moon:

Good doggie haha.

Once again, comments and suggestions are appreciated!
