hey. i was just wondering if you could re-anodize a yoyo so it is glow in the dark or glows under a black light. (like a yoyo string does) I don’t know much about anodizing so sorry if I’m totally wrong about the whole how its done thing. ---

No, I’m pretty sure that you can’t achieve glow in the dark with anodizing. You can get a yo-yo to glow in the dark by painting it or powder coating it. [This is a great website](http://frederico.dommel.be/anodizing.htm) about anodizing. ---

He said by black light. This means he could simply paint it white or anodize it yellow. If you want a true glow in the dark then follow what mrcnja posted. ---

To the best of my knowledge, anodizing it yellow wouldn’t make it [fluorescent](http://en.wikipedia.org/wiki/Fluorescence). Just because something is a certain color doesn’t make it glow under blacklight either. Granted there are some exceptions such as white will glow purple because it reflects all colors. I just did a test with my [Dragonfly](http://yoyoexpert.com/forums/index.php/topic,11640.0.html). The caps and the yo-yo are both a very similar shade of yellow. However, the caps glow bright yellow while the yo-yo glows a very dark and dull orange. None of the pieces of aluminum that I have put under blacklight have glowed (or exhibited fluorescent properties). So far I have tried the deep blue of my Superstar, the green of my Trainwreck, and the raw aluminum of a metal zero. None of them glowed. They merely reflected a small amount of light. I would have to assume that yellow would display that same property, that is, only reflecting a small amount of light and not glowing any. I will say that most of that was only speculative backed by a few experiments. One interesting trick that you could use, mrsnipes82, is soap. If you ever looked at a bathroom under blacklight you would have noticed that more or less all soap scum glows quite a bit. You could rub some soap on the rims and sides of a yo-yo for a temporary solution to wanting a yo-yo to glow under blacklight. Perfect for making a video. ---

would paint stay on forever or would it rub off. and will the paint make the surface of the metal rougher? and if it does stay on forever would I use oil based paint?
