Pooper, in response to your question, all of the paint I use is from Rust-oleum, I start with their filler primer, the high build formula. They have several colors of primer, I use the 249279 Filler Primer Gray. For the black base coat, I use the satin classic low sheen finish, with the smooth protective enamel, satin black color. The dark grey is Infoor/Outdoor Metallic, 244228 Metallic Charcoal color. The light gray is also Indoor/Outdoor Metallic, 7271 Silver Metallic. For the dry brush, I use their bright coat, metallic finish, in 7718 Chrome. Hope that helps! As far as the add on, I may do that later towards the end of the build. I prefer it without. I will probably be doing another LT helm as we get more HD files released, so I will probably save it till then. For now, I will be moving on to the chest. I have heard the sizing is a lot different on this one, so I have it printed out at a width of 380, and I am hoping that is big enough. We will see soon enough!!
