After washing and drying, I'm trying to reseason my castiron. Threw on a thin coat of olive oil and put in the oven upside down for 2h hours (180C/356F). After taking it out, I noticed these weird spots. After cooling off, they feel very mildly sticky. What am I doing wrong?

Edit: thanks for all the advice. I really should have read the FAQ first.
