For the Paintjob I just went and purchased certain kind of paints made for plastic and hard metal. Sanded down the metal plate, and slapped some primer on it and painted it. As for the plastic I just cleaned it good. and used a specific sort of paint on it that is designed for only hard plastics. I purchased all this at Home Depot.
As for making it “fit just right” you’ve got to use a dremel or some other tool to cut down alot of the plastic pieces inside the namco case. Since sanwa sticks are thicker and bigger than the stock Namco stick. You gotta do alot of modifications to both the stick and the inside of the Namco plastic case. This should help explain what I mean.
I presume it all depends on personal preferene, I enjoy the oct gate with bat top more than Square with Ball top. I feel I can do dp moves better, and I can do dashing alot easier. The stick with Sanwa parts feels just right for me, I enjoy the natural feel it has. But you are right it is difficult for one to put a PCB into the Namco stick, I did take a different approach for the inside. It’s not what you normally see in other custom sticks. When I get the chance I’ll snap a photograph of it. You’ll be suprised of what I did to the inside with the wires and PCB.
Much Obliged for the comments with the Paint.
