The next step was to fill in the gaps where parts of the apple shape were larger than the banana. I wrapped my logo in plastic wrap and filled the gaps with epoxy putty.
Tada! Here it is after painting. To paint it I used a glossy bright yellow spray paint and a softer yellow (summer squash) flat spray paint lightly sprayed over the glossy yellow.
Here is the almost cosmetically complete Banana Jr. I still have to paint the back and do some more stuff with cables on the inside.
