Pretty straight forward question. Did you use tint, or some kind of transparent vinyl. Do it yourself, have someone else do it?

 

I have seen colored flames done on the inside of a visor. It looked pretty neat but since the visor was plastic, it didn't look like it stuck 100%. Plastic surfaces aren't nearly as smooth as glass for the most part.

I have put a bar of black tint across the top of my visor. It worked well for me. I had to replace it once because the seal on my RF1000 pulled it back.
