Obviously, powercoating is not an option for rusty spokes.

I was just fooling around, hoping to read some astonished reactions. Sorry about that.

I always use stainless steel spokes for (re)building wheels. The quality of the rim and hub will tell you if it's worthwhile rebuilding it.

Otherwise, get rid of it and buy some factory made wheels. Eventually, you may want to tension them; they usually do need that.
