Some indoor tracks might take issue with the use of open flame and combustibles in the pits
. If you are using Losi Pink, Proline R3 or Panther "C" compound rubber you can make them sticky with WD40. Just spray or wipe a light coating on and let it absorb. I race at a track where we use slicks and the key to traction is getting dirt to stick to the rubber. Too much WD40 can be counter productive as the excess oil (if it is not allowed to sink in long enough) will repel the moisture in the dirt, I have found Simple Green to cause this too. The best bet is to get some Trinity Buggy Grip or Zip Free and go that route. Makes them nice and sticky with no fireworks.
