I'll tell you what I did with my swing arm and it has proven itself to resist scratching as well it looks good. What I did was went and got some spray on truck bed liner( black). Taped off where I wanted to put stickers/ graphics and such. Then I put the bed liner on as I would have if I were painting something. Looks good and I should get some pics to send along. But no longer have to worry About scratches. I also taped off all spacer and bearing holes as well as where the chain tensioner and axle go. It's just an idea. If you don't give it s second thought, that's ok. But it looks and works great. as far as added weight of the stuff, I can't imagine it's too much. But the scuff and gouge resistant properties of it can't be beat. Keep the good work up
