Alum vs Steel trap preperation

What are you using to Dye your traps in , Also Waxing them ?.

For clean up and dyeing I cut a elec hot water heater in half heat it with turkey fryer burner. For wax a alum kitchen stock pot heat it on a small propane burner with a dig thermometer to monitor the temp. My first year using a wax pot big differance from melting wax on top of water. Way better coverage with pot.
