Is there an easy way to remove the coating on my rear wheel sprocket cover at home?

Harpic won't touch it ... you need something like 40% strength sulphuric acid with a bit of glycerine added and reverse plate it at about 10 amps in that acid with lead as the other electrode .. mainly to remove the nickel under the chrome. A chrome plater will also remove by reverse plating in the chrome bath and it's fairly cheap.

Well my sprocket plate has been in "Flow Rust Remover" overnight, it has turned Yellowish in colour as has the solution that was pink.you have probably just converted the chrome layer. It's the nickel that's hard to remove.

Can't powder coat in as it is but could just paint it.
