I do alot of painting myself, custom paint on boats, cars, trucks, really whatever is thrown my way. You CAN paint the plastics, but like everyone said, any flexing, rubbing, bolt holes, edges etc. are going to be the first things to peel and chip. If you take care of your bike it would be fine for a few years. To be honest, I do enough trail riding that I'm going to have a local shop do what the call a "wrap" or "bodywrap" on it. I'm not sure if this is what you were referring to as a sticker or not, but it would definately be the way to go. What they do is print ANYTHING you want onto the vynil, in any color wether it be pictures, logos, decals, writing, flames, lighning bolts etc. etc. They heat it and wrap it around your plastics, then they come back with a thick, clear vynil that acts like a clearcoat on a car. It protects your graphics and withstands alot of abuse. A wrap is said to last as long as a paint job on the average car or truck (8 to 10 years) Depending on how you care for it and if it's left out in the sun or not. Besides that, if you screw it up in a small spot, or have to replace plastics, all they have to do is reprint and wrap the new plastic or piece in the scratch or whatever and you're back on the road within a day or two versus waiting weeks and spending an A$$load of cash on custom painting!
I'll post pics when I get mine done in the next month or so.. :thumbsup:
