- Spokes actually touch each other where they cross. As a spoke wheel rolls down the road it flexes slightly so those spkoes can't be glued together either.
- Finally, there is a pretty big Faraday Cage effect from all those spokes drawing the powder from getting to the hub. You will either have to get the gun tip too close to the spokes to get powder in there or try to shoot the part hot. If you try it hot good luck! You will likely get too much powder on the spokes causing a sag, run or drip besides exaggerating the first two problems I mentioned.
Bottom line, the best way to do it is in pieces. A bike shop doesn't charge much to lace them back up and true the rim.
