Always wipe off so much excess oil. Apply oil only when its hot...and a very little oil and smear it with a rag or paper towel and let it cool. Once cold smear another coat and then wipe away dry with a kitchen towel. Never do such generous apply of oil as the oil builds up a sticky layer...that's unhealthy. Didn't wanted to comment, but since you shared the link. I have been using cast iron for the past 22 years (yeah I am old) and a collector of cast iron cookware.
