I've had a Lodge cast iron skillet for about a year. A few months after I bought it I seasoned it with too much oil (I learnt later) and the surface developed some 'bubbles' that later started flaking. I've used it almost every day and while it is fairly non stick (I can fry eggs in it) I never managed to get a smooth surface on it. Here's a photo of how the surface looks
. While the surface might look like it's flaking, I do not see flakes in the food or when I'm cleaning it. Do you suggest I sand it and reseason it, or will the surface eventually smoothen out if I just keep using it?
