I often find surface rust on the gas cap o-ring sealing surface on the filler neck. I stuff a rag in the hole in case of sparks, which is seldom, and use a small cup brush on a die grinder. I also use a touch of dielectric grease or Syl-Glide brake lube on the o-ring if an old gas cap but usually just buy a new one for $12.
