Yeah you do.
The primered Endo looks sick. I love that. It's like somebody captured an Endo, and then primored it before painting it camouflage to be used as a Resistance reprogrammed Terminator. The Endo may not even give off heat. From the outside it migh just be cold metal. Imagine one of these painted up and hiding. We know what Terminator vision looks like. It might be hard for another Terminator to spot one like that.
If I had just one more Endo, I'd so do that. Anybody want to let me customize their Endo in friggin' camouflage? I'll even give it a bit of Boba Fett influence and make it look like layers of paint are chipped away from use and blast hits.
