My 5 qt Lodge Enamel Dutch oven just came in from Amazon today. Upon inspecting the inside of the dutch oven, I found 2 small pits on the inner wall. I was wondering, are these 2 pits acceptable? I am worried that the pits might let water seep in and cause the iron inside to rust. I don't want to abuse Amazon's return policy, but I would return it if it is a defect and will cause my dutch oven to rust down the road. Any suggestions?
