Believe it or not, I found the rocket boosters more difficult to finish than the blasters.
After applying the wood filler and sanding the appropriate parts smooth, I spray painted the blasters flat black.
I decided to use Rub-N-Buff for the silver parts because I liked how the blaster finished. I used painter’s tape to control where the silver went. It…mostly worked.
There was one particular part that gave me some trouble while painting as the model isn’t completely screen accurate. On the screen used prop, there is a is a black stripe on the middle of each side on a raised ring. On the 3D printed model, this ring doesn’t exist. I decided to use painters tape to create the black stripe on a part that would have otherwise been entirely silver. This broke up the silver on the sides and made it look closer to the screen used version. Here’s the booster after I applied silver paint:

On the screen used prop, the metal on the top is blackened and fades into the black. I tried to replicate this.
Here’s the screen used prop compared to the 3D printed version.
There are still some details I have to work on. I want to apply a black wash to make it look weathered and some “battle damage.” I may or may not try and apply the bluing to the base. Stay tuned to see the final product.
