This is the Gundam I used in my first digital diorama post. I glued the large opening part of the cockpit hatch to the chest and filled the gap with putty to match the anime design. I also filled in the small recessed molds in various places to create a simpler surface. For the white parts, I used Gundam White as a gradient over a base gray base. I tried spraying pure white for the highlights, but it didn't match the image I had in mind, so I tried spraying cream white mixed with a small amount of yellow.
