I tried following this method and ran into some problems...
1) Don't skip the anti-seize on the smaller bolt you use to hold the nut straight. The epoxy may bond better to the threads than the bolt did to the head, and then you end up with an impossible-to-remove bolt.
2) Don't skip putting the lug nuts back onto anti-seized bolts - otherwise if you get epoxy on the threads, you now have to scrape that away.
3) The metal caps can actually be popped off the lug nuts, which makes positioning and epoxying the nuts far, far easier. Just put a smaller bolt into the lug nut, put the nut on your vice, and tap it out.
4) If using Walmart pizza pans, give them a good coat of paint - after two weeks of snow and salt, my covers are showing an odd pattern of rust.
However! Between some epoxy and some poor welding attempts, I did get all 4 wheels of my xA covered with 16" pizza pans (on 15" wheels). The bolts give them a big advantage - you can use the exact same setup between two sets of rims (if they're the same size).
