On a show last year (I know long time ago) Gen did a wall that was metal and then did a rusting technique on it. It looked amazing and I'd like to do it for my Backsplash.

Problem is when I ask at the paint stores they look at me funny. For one, why would you want rust in your kitchen (I like industrial) and two it sounds too complicated and they've never heard of it.

Wondering if I could get the info on products and technique.

Thanks
