Another Rust Question
Okay... inspired by JKC's battery compartment makeover... I'm going to try to get to some surface rust to clean up the truck. Read through all the rust posts (there are a lot!) but still had some questions:
Naval Jelly vs Ospho?
- With Naval Jelly... you have to rinse it off in 15 min? Ospho you just leave on for 24 hours? Which is more effective?
- Spraying the Ospho on the undercarriage... can I just spray everywhere or do I need to be cautious about rubber/aluminum/painted areas?
- I've got a little bit of surface rust creeping on the engine side of the bulkhead... okay to just spray that down even though it's painted there?
Thanks in advance!
