HF stands for High Fluorocarbon. There are 5 main waxes in this category, which are fluorinated hydrocarbon blends having a high percentage of a low-melt point fluorocarbon additive - a result of Cera F technology. The waxes are unique because they provide fast acceleration, work in a wide range of temperatures, and are durable and dirt resistant. HF waxes are excellent when used alone, but ideal when used in combination with Cera F as an over layer. Availble in 40g or 180g bar size.
