Thought about that too, im just nervous about spray painting my whole bike hahaI would also love to put a VERY light coating of smoke on my tail light, I still want to be able to see the red but just darken it up just a hair..
If you need to mask your entire bike to paint a 4" turn signal you really need to work on your spray skills. With patience really good work can be done with good ole vhthow would you spray it? just cover the WHOLE bike in newspaper?
