I haven't heard off it either.
I use a product called PPU Dry Wash and Wax (Perfection Products Un-Ltd)
The Perfect Wax Waterless Dry Wash and Wax
- Clayed Finish
- Clear Coat Safe
- Cleans, Seals, Polishes and Protects in one Easy step.
- Removes: Oxidation, Bug Marks, Road Tar,Tree Sap, Bird Droppings and Swirl Marks.
I have used it on my 82 Pace Arrow, My 64 Deville, And my 99 Deville Concours. Easy on and Easy wipe off.
I got it from A car show I went too. I buy it there every year. I use many of there products and have not been disappointed.
I don't work for them in any way. I just buy there products.
