Merci. Il y a peu de choses que j'aime autant que la rouille.
Strange... could it just have been rusted?
My theory is that the yellow line has been traced first, then the hole has been cut with a welding torch, and the rest is down to rust and acid rain.
This is just great! love it! An acid perhaps?
I'd say that the whole has been cut with a welding torch, and the rest is down to standard corrosion.
