I've finished a grasshopper engine and need to rust protect the mild steel parts, I don't want to paint it as I don't get good results with this.

I'm thinking of heating the parts and dipping in oil, or any other suggestions please.

Bob.

Heating and dipping in oil can give a nice black finish. I usually use linseed oil on a small piece of cloth, heat the part and apply the oil until I get the finish I want. In my experience this will give some rust protection, especially if you wipe a bit of oil onto the parts occasionally.

I used metalguard on mine as advised by Jason.

This means the original steel finish is retained.

Very little paint used on my hot air motors that are stored in my uninsulated workshop, rarely is there ever a problem with rust. I haven't, but I have heard of aerosol hair spray being used as a rust preventitve, it's not hard wearing, but OK on items that are not handled much.

… 'I have heard of aerosol hair spray being used as a rust preventive' …

Used this myself over the years, nowadays I use clear lacquer spray available from any DIY/Hardware/ motor shops, hard wearing as it's made for car paintwork coating.

Lanonin is a good surface protector for polished metal parts of an engine if you want to keep the shiny silver finish.

From tests carried out in ME from long ago, ' Three-in-one' oil was way ahead of anything else.

I have just removed the tarnish off a small steam engine and coated the parts in metalguard as Bill has done. One of steel parts is flame blued for a nice contrast.

I quite like bare or blued steels. A huge number of sins can be covered up with filler and paint.
