Have any of you ridden a track treated with Soiltac? We are building a dual slalom track and are deciding what the best way is to keep the dirt compacted and the dust down. I know you can use Mag Chloride but it is a process you have to constantly do over and over. I found Soiltac today while researching some things and wondered what it is like. They say applications last a long time, but I wonder what it does to the track surface??
