Very very little oil (no poodles). I use a paper towel to spread it thin. You can even bake the pan upside down to ensure no poodles can form if you have non-level bottom of the pan. Use some refined oil or lard. Goal is to keep it below smoking point. It works to reseason the pan after minor damage (not yet rusted, but lacking non-sticky surface). I use the pan almost every day, so I don't have experience with fixing heavier damage. If the pan gets sticky to the finger afterwards (it shouldn't if you avoid poodles of oil), don't worry. It will resolve itself after a few cooking cycles.
