I am new to cast iron. I know people sand them and make them good as new, but I thought I was buying one not needing labor like that. I don't have the time or tools or energy or patience for that. Did I get ripped off by the seller? It's hard to photograph but there are little indented areas of silver where the black stuff has chipped away. With work, it looks as if more black flakes off. Are these spots extra prone to rust? The pictured spot is the biggest, then you can see numerous smaller ones and there are more not shown. They are mostly on one side and in one area of the wok. It is Lodge brand. I know other brands are better but I wanted a traditional shaped wok in medium size. I hope the answer is just reseason it and use it!
