surface rust, best way to remove

[stinkydogfilms]

Hi,
What is the best way to remove surface rust without having to go to a machine shop?
Is there anything I can spray on that will remove the surface rust and something to spray on to help prevent rusting?

Thank you,
Mike

for all those cylinder bores and mating surfaces and rod surfaces... I'd say you're screwed without honing/decking/polishing all of that to fresh metal. all rust removers will etch the metal.

To prevent rusting... anything oil. Spray some used motor oil on everything every 3-6 months and it should keep the rust away. Obviously keeping stuff out of the elements will help loads.

You need to have those engines goto the machine shop. No chance. They need to be hot tanked and honed.

Yep, nice pile of core motors there.

Chainsaw bar lube works the best to prevent rust after cleaning and machining. It WILL LAST FOR DECADES.

The shredder at the scrap yard will take care of that too, but if you want to use those engines they need to go for machine shop work. The required surface finish is not something you can get by wiping something onto a rusty surface.

I've been meaning to ask about that. I saw a jug on sale for a relatively cheap price some months ago, but just from shaking the jug it seemed like the oil was the same consistency as motor oil. I was figuring it would be some kind of thick gooey spray-on stuff. Is the runny stuff the right stuff?

It is a bit thicker than most oil and a bit gooey and stringy. It was designed to cling to metal and displace water. Eventually it hardens up its not easy to remove.
I use it for undercoating some of my rides, blocks, cranks, rods, pistons, pins, cams, lifters, any machine surface, threads, splines.
