It's good stuff, Joe. I contacted the company - Rislone Technical Support to inquire about its use in my '34 with Babbitt Bearings. Their response >

"Thank you for reaching out to Rislone Technical Support with reference to which product to use for your 1934 Ford Flathead to best protect the Babbitt Bearings, P/N 4104 Nano Prime or P/N 4405. We would recommend the P/N 4405 Engine Oil Supplement with Zinc Treatment, it is exactly what you need for the best protection of the Babbitt. The zinc ion adheres to the metal surface. Under heat and pressure, ZDDP forms a microscopic glassy, phosphate layer that fills in the peaks and valleys of surface roughness, improves lubrication and forms a sacrificial wear coating. For your convenience, the link to the product on our website is below. It will direct you to the product overview(s), as well as directions for using this product, FAQ, technical information, and the SDS (Safety Data Sheet)."
