Last week on the rear of the PE Super I noticed a water spot, there is a white ring and a minor surface rust spot about the size of a quarter. I looked up and noticed where water was seeping in around the flue collar at the ceiling. I think (hope) I found the leak culprit and took care of it, the true test will be this week, we have a big rain event due in, fingers crossed no more leak. What is the best approach to take care of the blemish on the stove, should I use steel wool on the rust spot and then hit it with some stove paint?
