If you haven't used Plasti Dip before check it out. It's like using spray paint, but not permanent. In this case it's semi-permanent. It lasts as long as you'd like it to, but peels off in the case that you no longer like it.
It's as easy as mask, spray, peel away tape and enjoy!
Below are pics of a quick run on my bike. I've used this stuff many times before and couldn't recommend it more.
