Last year sometime there was a topic on "rust". If I remember, it gave a formula for making "something" to dip metal into to rust it. I had marked it, but evidently it didn't transfer to the new forum and searching for it under such heads as rust /weathering, etc. brings up tons of stuff but not the particular post I'm looking for. I want to rust dip various metal cars, etc. Can't remember if this 'stuff" also worked on plastic. I'm pretty sure it was on this scenic forum. Can anyone help?
thanks
