George, make sure the 10" skillet is hot before you press and you are golden.
Wipe off the outside of the 10 inch skillet the same way you do the inside.
All of those surfaces need the same treatment, so you are doing a good job to expose the outside the same way. 
Sounds like you are on your way to discovering the true potential of cast iron.
Thanks.:-) only problem is, I need the 10 inch skillet for eggs while bacon is cooking. A reviewer for $20.00 bacon press on amazon.com wrote, "Use the bottom of an 8 inch skillet...Less than $9.00 and easier to clean up than messing with the two screws.
weight is comparable to the bacon press."
So, yes, I'll use a skillet and yor tips...gives me an excuse tobuy another skillet.:-)
