Fluid Film is the perfect lube for combine chains. It will never get gummy or sticky so dirt won't build on top of itself. It will penetrate to the inside of the chain and provide long lasting lubrication. It resists fly-off and will not be readily washed from the surface. It will not freeze and will prevent chain jam ups due to water frozen in chain links. It is so effective in harsh environments it was documented as having extended locomotive drive chains in salt harvesting machinery by up to 300%. Using Fluid Film will help extend maintenance schedules and is great for storing equipment indoors and out.
