powdercoating will be about 20-40 per arm, but they will last forever or until you bend them, whichever comes first. the factory bars and arms are not powdercoated they are painted, so that means they at least need to be stripped or sandblasted (adding cost to however you coat them) bethviper is correct you need to start with a good substrate to get a good top coat. if you skip steps they will not last and not turn out good, so dont be cheap or in a hurry while prepping them. i cant stress that enough. (20 years of bodyshop experience talking) i had a set of arms chromed last year in lansing at adams plating, inc all prep for 60.00 per arm, and they look great just remember nothing else on the sled is chrome and polished aluminum doesnt come close to what good show chrome looks like. so they will look odd on your sled unless you are a super clean freak. my powdercoaters number in greenville mich is 616-754-2229 talk to pat or jim, they do awesome work. i have had alot of work done over the years there and sent a few forum users there as well. all very happy. ski
