Oil rubbed bronze clawfoot tub feet
Q. HI!
MY NAME IS DEBBIE!
I HAVE AN ANTIQUE CLAWFOOT TUB AND I WAS WONDERING IF THERE IS A WAY THAT I CAN REFINISH THE FEET TO HAVE AN OIL RUBBED BRONZE APPEARANCE. I HAVE SENT THEM TO BE SANDBLASTED TO REMOVE MANY YEARS & LAYERS OF PAINT, TO RESTORE THEM TO THE ORIGINAL CAST, BUT I DO NOT KNOW WHERE TO GO FROM HERE. IS THERE A WAY TO ACHIEVE THIS ON CAST IRON?
THANX SO MUCH FOR YOUR TIME!
