AMSOIL Heavy Duty Metal Protector engine compartment (1 Viewer)

[LC neophyte]

I would like recommendations on what parts should be treated (or not treated) with AMSOIL Heavy Duty Metal Protector in the engine compartment. I live in the salt spray Midwest and have already treated my '18 200 LC with Krown on the underbody. I would like to protect those connections or tubes that are susceptible to corrosion. Any experience with AMSOIL Heavy Duty Metal Protector? https://www.amsoil.com/p/heavy-duty-metal-protector-amhsc/
