Quickest way to create Rust??

[44GPW]

Yes i know this will sound like a very strange question, but i have some re-manufactured GS body brackets in steel that i would like to have the "pitted" look so it matches the rest of the original body fittings.

 

Whats the quickest way to get that rust pitted, aged look?

Salt water?

[ChasSomT.]

Brake fluid!

[Marmite!!]

Ammonium Sulphate fertilizer

Brake fluid!

 

I thought it was the other way round, heard of using brake fluid to remove rust but not forming it??

electrolysis method ?

[griff66]

leave it in the garden

[mcspool]

leave it in the garden

 

better still, strip it of any paint etc. and bury it in the garden

[griff66]

ah but would reduced o2 buy burying object hinder rust development

[ruggyjohn]

fertilizer is the best, will rust in a matter of days.

Thanks for all the suggestions guys.

 

So if i go with the Fertlizer option, do i just submerge it in a bag and is it best to be dry, damp or wet?

 

How long do you rekon until the rust is so bad it leaves pitting after being cleaned?

 

Thanks

Restore it then leave it out in the open for a while:D

Like i said electrolysis. Connect to positive side as sacrificial anode while possibly cleaning some thing else. once desired amount of rusting pitting has occurred simply reverse current and it will clean back to good steel dry and wipe off and its ready for painting

I'd cover it in Battery acid.

 

Many years ago, i collected English Civil war artifacts, i had a nice original Helmet and front Breast plate, i had to buy a reproduction back plate and wanted to age it to match, I dug a hole in the garden, put some rock salt in the bottom, layed the new steel plate in then tipped more salt on and covered with earth. some months later i aquired an original 17th century back and forgot about the buried one.

5 years later my dad dug it up by mistake and it was like tissue paper and just fell apart. would have looked good on the Time Team !

 

SO DON'T LEAVE IT TOO LONG !!

If its pitting you want. Why not just hit it with a small pien hammer? Pig muck, that will rust pit and dissolve anything.

[alixcompo]

Yep battery acid or lemon juice

[scammell 7377]

strong neat battery acid ive known a leaking steam engine rivet soaked in it overnight hold 120 psi 14 hours later (dont try that at home ) treat with great care though dont spill it on your skin eyes etc

Water/vinegar mix. It will be rusty overnight.

A company my father had dealings with, used to age 'genuine antique' coaching horns by putting them in the urinal:-X

Corrosion tests use a salt fog test to enduce rapid rusting.

 

 

 

You could try looking for local engineering companies with a mini test chamber.
