Hey Horus. I haven't read the replies to your post, so I hope I am not rehasshing something someone else said.
First I love the build. Very clean, and Rubio's barrels are awesome. Just make sure you get some PE Grills over the engine covers.
Second. If you are to attempt zimmerit, I would recommend in the future that you do it before you assemble the hull and turret. This makes applying the zimmerit much easier, and reduces the chance of mishandling.
Get on me on MSN, we can go over it.
