My son and I used to use Buggy Grip blue at the clay track we run on but lately I have just been cleaning mine as I feel the BG gives you too much grip for the first few laps and I am more consistent without it .

When the track has moisture in it we run slicks and it has a ton of grip without any sauce at all but sometimes at bigger races it can dry out and then pins and saucing the tires is the way to go .
