Sorry.....I was referring to the Original Post,
1. Mineral Spirits
2. Paraffin Wax
3. SAE 30 Non-detergent motor oil
heated up, melted and applied. I'm not sure if waxoyl uses same formula, but judging by it's name it might be comparable. ( they supposedly use chemical rust inhibitors suspended in wax).
