Any one have experience with Cosmoline Rust-Veto 342? When cleaning the engine bay and behind the splash guards I figured out the surface rust was actually dirty Cosmoline. The product sold today isn't the same, but apparently still tough to remove and has good feedback. While I have the battery tray and the brake booster out of the way, like to put down some protection. I have used LPS-3, but didn't protect worth a darn. Figure ask over here and get a more recent opinion.

Thank you all in advance!
