What to spray onto metel immeditely after removing rust?

[Rusty30roadster]

I use pb blaster30wt engine oil, or wd40 after rust removal.

I have a 100 gal e-tank and just ran 4 trans cases and an f100 steering box through it. Flash rusting is a real problem in southern ca because parts seem to dry and rust instantly. Stromberg carb bases are my nemesis when it comes to flash rusting. After a run, I always rinse with the hose really well, dry as much as I can with a towel and spray with pb blaster or wd40 is my 2nd choice. When I get around to painting, I will wipe the oils off with acetone or alcohol and primer with vht high temp engine paint. It contains acrylics and dries super fast.

When I’m out of spray products, I use 30wt engine oil to prevent rust. Apply with a rag.


My advice, don’t over think it or buy more unnecessary products. Slap what you got on there and it’s usually fine as long as you remove it before painting.
