So... I've heard "pitting" is when you know you are not staying on top of sanding down your flame rods. I just sanded mine yesterday -- here are some of the before pics. Everything just looks like it has a thin layer of black soot on it (and some dryed up anti-seize paste in the threads) -- I don't see or feel any pitting on the rods though. How bad is this pitting supposed to be -- should I feel bumps with my finger? How do these flamerods look? I am sanding these about once every 4-6 months. After sanding they are smooth and silver/gray (but before the sanding they feel smooth -- just don't look silver/gray).
