I like Starscream, G1 Starscream is a great character and if he's still the same in later versions then he's great. His character is someone who would normally be easy to hate, but he ends up being likeable because he keeps trying and keeps getting humilated.
It all depends on the job in question. Screamer here was lots of larger panels so I primed him woth grey primer after diasasembly. Any parts that didnt get cover where then hand brushed with Fortress Grey, after the priming I used Enchanted blue, Blood red, Bad Moon yellow, and various other hades to give hi the classic G1 scheme.
Some figures I do not pull apart as 2 many small parts turn into a huge mess and its just as easy to hand brush the entire piece.
