I've done a few customs in my life, but here's my first SUPER POWERS one!
I put regular Supes next to him to show the difference in blues. I WISH I took a before picture, because I actually dug this figure out of my parents attic and it was demolished, lol. This was taken completely apart, sanded and painted! I was getting really frustrated with the brushmarks, so I finally gave up and spraypainted the blue!
Then once it was dry I carefully taped it off and sprayed the red. Nice and smooth that way! The only original color is the skin on his head because that was cast in that color!
