any one ever paint rubber fender plugs to match their bikes?
Or know anyone that sells them?

 

I found a color close enough to my bike in Krylon and sprayed a couple about 4 years ago.I've had to respray one of them once since then. They actually match pretty good.

 

No because I've never used any. And I'd imagine they're black and so is my bike.

 

I welded the hole shut and re-painted the fender. Smooth now.
Extreme maybe, but better than a band-aid.
