Rusty nuts bolts and misc small parts

[JORGIE95961]

Ok so the deal is here that i soaked a coffe can full of rusty nuts and boltd in vinegar for a few days.. then i filled up the jug with wAter and agitated them till all the rust came off.. that was the easy part.,... once the rust was clen i threw them in the oven so they copuld dry fast.. .. they rusted within 5 minutes .. my question is... How the heck do i keep the rust of.. I could soak them in some oil, butt i like to keep my vehicles clean and i degrease and wash out my entire truck everytime i wash it . Do i rattle can it ? I understand that I can just buy new ones , but im just curious as to the best way to "restore" old nuts and bolts.............
