You could leave your reciever in the white for a bit but be extremely careful where you leave it because rust can pop up overnight, so leave it in a very dry place, I left receiver s lying around in the white for a few months and never had any rust. We also sell zinc phosphate(grey) and manganese phosphate(black) park solution, if you are also interested. Its not up on the site yet until we finish the overhaul so please call us if you are interested on pricing.
