This is a bottle of SXT Racing 3.0 Foam & Rubber Tire Traction Compound. SXT 3.0 was developed to provide superior performance in low odor environments for both foam and rubber tire class racing. It has been engineered, tested and proven to be compatible with Jack tracks. No worries about setup changes when switching, as SXT 3.0 provides the same on-track feel and performance as Jack. Another benefit the SXT engineers have noticed, is the ability to rejuvenate old foam tires. They tested 1 or 2 year old foam tires and soaked them a couple times with SXT 3.0 and they can potentially come back to "like new" condition. Simply run them once and you have race ready tires that you usually would have thrown away! Carpet Foam and Rubber Tire: Apply SXT 3.0 to clean tires. Typically the entire rear tires and a portion of the front tires (starting at the inside edge) are coated, depending on traction conditions. Soak time before wiping is also dictated by traction conditions; longer soak = higher traction. Start by soaking the tires for 15 minutes, timing it so that you wipe them 10 minutes before racing. Asphalt Foam: Apply SXT 3.0 to tires. Typically the entire rear tires and a portion of the front tires (starting at the inside edge) are coated, depending on traction conditions. Apply SXT 2.0 on top of SXT 3.0. Soak the tires for 20 to 30 minutes, timing it so that you wipe them 10 minutes before racing. Shorten soaking time if track is high bite. Recommended Use:
