I recently restored a cast iron skillet, and seasoned it using flaxseed oil (prior to reading deeper on this forum). I'm not particularly impressed with the flaxseed, and am going to re-season with Crisco. Do I need to strip the flaxseed back off, essentially starting from scratch with the Crisco, or am I fine to just season on top of the flaxseed. Having just stripped, cleaned, and seasoned the pan, it's obviously not in poor shape, but will the Crisco bond sufficiently to the existing flaxseed seasoning, or do I need to get it back down to bare metal?
