You might want to start from scratch seasoning your pan. It's not difficult, especially if you have a self-cleaning oven and/or an outdoor barbecue grill.
You could run it through a cycle of oven cleaning with your self-cleaning oven to remove all the old seasoning or put it on your outdoor grill on "blast" temperature for a little while to achieve the same end.
Once you've done that, wipe it down and reseason with a nice even coating of Crisco. That's what I use. Put it in your oven turned upside down, with a layer of foil under to catch any drips, and "cook" it at about 325F for about 2 hours. Check it at about 15 minutes to see if there are any drips you might want to dab off. Let cool completely.
If you're starting from scratch, you might want to go through this process a couple of times to build up the seasoning.
After that, use it, use it, use it and, in time, it will be just as nice as any Teflon pan you could find anywhere.
