Thanks, Kelly! I remembered last night that I’ve got most of a roll of flashing somewhere. I needed about a foot for a repair a couple years back, and it was cheaper to buy a whole roll mail order than try to get just what I needed locally. Now I just have to remember where that got to.
Thanks, Don! I don’t think I want to actually pierce the metal. I think (having looked at this some more) that I prefer dimples, which I why I tried the nail set. But we’ll see what I can produce consistently. It’s definitely going to take more practice.
