RE: Plasticized dope mixture
I have found Scotchbrite to be better for me than steelwool. The Scotchbrite (SB) leaves no metal bits to rust and is available in different "grits" at auto refinishing materials shops. The SB is identified by color. The green variety available at grocery stores works fine for me for most uses, as well as those in the kitchen when I do the pots and pans. I think the SB is an abraisive grit in a nylon nonwoven material.
Good luck
Sincerely,
Richard
