Is there a quick method for rusting steel? A chemical? I have a sheet of steel (14 x 44) that I am trying to get a nice light rusted surface too- in about a 3 days time.

Never tried this but, knowing a little about chemistry, would suspect a mixture of peroxide, vinegar and salt will do the trick.

i'll check it out- (dang..now I owe my wife an appology..she mentioned this last night)... Embarassed

Now if i spray clear-coat on top - this should eleminate futher oxidation..right? I am looking to get it rusted - seal it, screenprint on the steel, then seal it again.

I think the Hoodriders would urinate on the bare metal.

My wife used to be into crafting and we always just used vinegar and water. It would usually start having a nice mild patina in about a day or two. We would just spray it outside and leave it.

I'm no expert on this, but you would have to make sure to wash the salt off really well first. The peroxide is there to supply oxygen to aid the rusting process.
Once you seal it and no oxygen gets to it, rusting should stop.

You're right... female urine is more acidic than male urine.

remember Murphy's First Law of patina: the speed at which a piece of steel rusts is inversely proportionate to it's value, and/or the amount of effort expended to prevent oxidation.

Strip all of the paint off an 88 Ford Tempo, and you can tailgate sanders for a decade of midwestern winters without any apparent damage to that bastard, yet the freshly repaired and painted doglegs on your barndoor will turn to lace after driving past a dew-covered front lawn.


Therefore, if you want it to rust quickly, screenprint it FIRST. once that scrap of steel has value, it will begin to disintegrate in four minutes or less. then, screenprint it again.

Think good point...plus - the this will aid with the increase in value..(and where the heck have you been?)

I just built a slate fireplace floor to ceiling. I used 3/4" angle iron as trim around the fireplace opening. I was going to paint it bronze or something, but since the slate I used had a bunch of marbled rust in it, I thought I'd just let it rust. I threw it out in the snow -it took about 3 weeks, but it's got a nice, even coat of rust on it.

make sure your piece of metal is meticulously cleaned and bare to get an even patina. I'd sand it first followed by a vinegar wash to make it thoroughly clean. Then wiz a way!

I use hydrogen peroxide and table salt then mix it into a slush. I use it to age tin and thin metal. It starts rusting/aging in about 5 minutes. I usually let it set in the mix for an hour or so. The pic is crappy, this was clean tin to begin with.
