WPL Race Ready Tubeless Sealant is a nano-technology powered, fully bio-based formula harnessing natural fibrous tissue that seals punctures of sizes varying from 1 micrometer up to 1/2” in size. Nano particles fill pores in the rubber tire preventing air loss over extended periods of time, and larger particles are emulsified in a solution engineered to perform in a very broad temperature range, ensuring a hassle free race run every time.
