What kind of paint do you use to pain the sides of the TE stick?
Not using paint.
I bet you could use “Vinyl Dye” – They sell it at automotive stores in spray cans. I used it to “dye” my 360 controller black before you could buy black ones. It came out amazing and never rubbed off. Import Tuner kids use it to “dye” their dashes different colors, so it holds up to the sun and other elements as well.
I say “dye” in quotes because it really is more of a paint, but it bonds with the plastic.
I’d give that a try. I recommend getting a matte over a gloss though, the gloss just looks cheesy/cheap.
