the wax i sealed my bottle i sent to neil just had parofin wax and an old blue candle mixed in i will say it dosent stick well and i coulda used more blue. but it did the job.
I bought some food grade cheese wax about 6 months ago for dipping bottles, I hated it. The wax melts if the weather gets to hot, It melted in my car and made a mess. It's a pain to get get off the bottles, and you have to dip it multiple times for a good seal.
Over all I decided to go with shrink bands, But thats just me. Rick b
