I have removed my boom to redo the outhaul. While I am doing this I am also cleaning and waxing the boom. Which brings me to the end caps, they appear to be brushed aluminum but through the years a little blackish look to them. I am going to paint them, is black or aluminum the color? I am leaning towards aluminum.
Mine are black.
Glenn : The end caps came from the factory with a flat black paint!!
