let me see if I understand this correctly? you are risking blowing up your house and/or a fire to save a few bucks on developer? Yeah I would say it is the right choice..as to the developer, no it will not hurt it..butane is not an oxidant, it might make your plastic bottles brittle after time...Basically I would say you are just waiting to see which one lasts longer your house or the developer..Good luck, I think you will need it!(posted 8389 days ago)
