Hi all.
Last weekend I went to my local “Radio Shack” to get a bottle of etchant (Ferric chloride) for some Campbell corrugated siding.
They said corporate told them a year ago that they should stop selling it because someone could make a bomb out of it.
That being said what could be used to do get a rusted and holed through look for corrugated aluminum?
I want to make a fence for a scrap yard on my layout.
Thanks.
