Chemically Rusting Galvanized Metal
I am a home owner that is creating a pool room in a new home. I am using corrugated Galvanized Roofing material for an architectural finish on some walls. The material was new. I have tried using a diluted Bleach and water solution with almost no result. Subsequently I tried a solution of Muriatic Acid and water with no real rust appearing either. can you suggest a way to easily rust this material. I have approx. 40 pieces 25" x 36".

You can try 20% iron(III)chloride solution!
Mixture of 20 gm copper sulphate ⇦this on eBay or Amazon [affil links] /10 gm salt/100 ml water can be used too (if galvanized =zinc plated). Good luck!

eBay
or
Amazon [affil links] , I believe letter 30790 gives more details.
Good luck.
