Yes, the two Bio Zap(p)s are the same. It's really good stuff. So are Restore A Finish and Feed and Wax. My husband did our kitchen cabinets and they look new. We used Through the Roof to handle leaks around the flashing and chimney and it's still good ten years later.
We met Johnnie at a Home show in his later years. He was quite a character, but serious about finding solutions for people. His daughter, Trudy, is following in his footsteps. Many of the things talked about were used by them, so they know how well they work.
I want to order his new book, too. The old one covered a lot of common household problems, big and small.
