Haven't done it - yet - but was considering it for a mismatched set I have.
Blue or green tape to mask the braking surface (and spokes if needed)
I was going to use a 2-part spraycan epoxy if I can find it. You have to shake the can to break the inner seal, and you have a time window to spray.
Then bake them. Attic in the summer is a good place. I use a quartz space heater - heats objects, not air.
These are just my untried and unproven suggestions. But let us know the results.
