Good increase of grip over other traction compounds and seams to last a whole 5 minuets race peaking about 2 minuets in. For carpet indoor apply 20minuets before racing as a good starting point and I don’t wipe the compound off as it’s almost dry after 20 minuets the let a 2 or 3 lap warmup clean any excess off and bring grip levels to where they should be. As a side note be weary that some people keep the bottles and refill with other traction compounds also the bottle has a wide opening so be sure to tighten the lid after each use as if you knock the bottle the entire contents will come out immediately. Set your car up to use this and you shouldn’t have any problems.
