Yup. All of my early issues with flaking or a rough surface was due to putting oil on cold and putting too much after to trying to repair it with too much seasoning.

Eventually saw directions that explained the right way to season as adding lots of thin layers like spray paint, not a coating like house paint. Also explained adding oil after heating kept it from humming ip and causing the same issues. Doesn't even have to be at a high temp either, just wait till it is radiating some heat before adding the oil.
