To gain comparable lap times and information during testing an consistent level of grip is indispensable. But when testing outside of a race weekend, an on-road asphalt track normally offers a poor level of grip at the beginning which increases lap by lap which makes a comparison of test results quite difficult. Xray/SMI team driver Dirk Wischnewski, a two-time European Champion in 1/10 scale nitro on-road racing, was facing this problem also. However he has come to a solution which makes his testing very effective. Wischnewski is using Track Max which is a special track treatment compound from Dutch based Tornado. Dirk had this to say:
For a while I have been using Track Max of Tornado on my regular test track and I am enjoying a high and unchanging level of grip all the time. It only takes a few minutes to spray Track Max on the main parts of the track where a certain amount of traction is needed. The grip level will increase rapidly to what you know from big race meetings. Especially after a long winter period Track Max is a perfect stuff to get back to reasonable conditions.
