if you want something to fill the wheels with that will not fall off in a 4 - 5 years (bondos life expectancy) possibly... use JB weld, it is close to the consistency of the wheel alloy and will bond like crazy... you can use Quick JB if you are not patient enough to wait a day for it to cure, but i like the original much better...

btw... you guys know that JB weld will conduct electricity ? hah...
