website : vegausa,com/ it has a lot of info. . Chemical prep depends on type of track and its surface (asphalt -dirt) maybe even track rules. take a look further here on Bobs' dirt oval - under tires and asphalt sprint .What is the difference between vega yellow and whites, and what if any prepping would be done.
What chemical would be used?
If someone would be so kind as to share what they are using as a pre race wipe*(if any) on the MCS tires , Pm me if you would rather. Thanks, John
