I ended up getting Duck brand at Sears, though I dislike shopping at HD,
think I will make the trip there as suggested by one poster to search for
Nashua brand.

Wart medicine, UGH. I've had no luck with that stuff, tried Compound W and
something else. Makes a mess out of the bottom of your foot.

The duct tape took about 1-1/2 weeks and really showed a huge improvement.
When my doctor mentioned it, I thought "oh no", what kind of quack did she
become. She was right on the money though.
