lps is more of a waxy type that I used in the inside of my door panels and inside if my quarter panels and under the car as well.
Con of this product it adds weight to the car. because it is a wax and it not a film. Notice the only plus side of adding weight is when I close my door it make a clear clunking noise and doesn't rattle like rice sound. but I hate adding weight to a weak trans.
these are paint-type on options I would say they add weight as well but it is for really bad rust work best under or behind a panel of a car and not a painted panel surface.

They have a product called rust bullet black shell that I think would work great for coating the under carriage/ wheel wells of our cars.
