Apologies if my post is out of order, I did the majority of this back in October and never got around to posting about it.
I wanted to highlight some more things I learned during my build that might help people.
First, let's talk about lenses and the best way to color them. The stock Spirit pack (at least mine) came with white plastic lenses for the cyclotron and a white piece of plastic with a blue sticker for the power cell. No good.
An easy fix that I found turned out really well was to get some Testors brand clear spray enamel, they sold it in red and blue. I found it at Hobby Lobby and I think the total was like $5 or $6.
The blue sticker on the power cell lense peeled off pretty easy and I hit them both with their respective colors. they turned out really well, let plenty of light through, and since I was using stock parts they installed very easily.
So yeah highly recommend the spray enamel from Testors.
