I don't want macro-plastics in my food

In high school, my group of friends would occasionally have cookouts and one of the other guys made a grill like this, tho out of an old, metal oil drum his dad had on his property (dude ran a machining shop so had hella random junk in the backyard).

He didn't clean the drum tho, so nobody else wanted to eat anything he cooked on it. 🤣

The shape of this drum does not appear to match in the two pictures
