A small note about using sun protection as traction compound.
The benefits over conventional tire additives are that it's guaranteed non harmful for you skin and that the effect stays a lot longer compared to the purpose made stuff like Paragon, CS electronic Max Grip or Corally Jack the Gripper. Unfortunately it's more or less odorless - I love the smell of wintergreen
Sun Protection is a very creamy liquid and you need to leave it on for a while for it to really penetrate the foam, even better if you have a tire warmer to help this process.
You will have added traction for 30+ minutes.
