Slick 50 Recharged High Mileage Engine Treatment
1 fl/oz of that, mixed with ~4oz of paraffin, 2oz of paraffin oil, and a puck of Mr. Zogs. I think the Mr. Zogs makes the biggest impact, because it softens the wax the most. Smells nice, too.
I'm getting a full month out of each dip, which is around 400 miles (per bike.) meaning the amount of materials I bought should last until the 2030s.
