I have a rebuilt engine that was hot tanked and been on an engine stand in my shop for a few years. The engine has developed some flash rust. I scrubbed it with SEM Rust Mort, followed by a thorough rinse. I then washed the engine with Dawn and a red scotch pad and thoroughly rinsed it again. The engine has a mild coating of flash rust, what do you guys use to seal or get rid of this? I was told OSPHO, but I believe OSHO must be water rinsed to neutralize, which would create additional flash rust? thanks guys.
