We have a business buying and selling hard core race parts.The LPS 3 says no rust for three yrs and it works.The down side is it is paraffin based and a PITA to clean off.Store the engine the same way you would store a expensive firearm. Don't use WD-40 as a rust preventative because it will evaporate in a week and give you a false sense of security. I store freshly machined engine parts with a liberal coating of LPS 3. Seal it and install the engine in a plastic bag as outlined previously..
