E-Thirteen created tyre plasma after being sick of goopy slop that didn't live up to its claims. This is a unique mix of acrylic resin with self-linking properties. What does that mean?? It'll quickly and efficiently plug any holes preventing air loss. You can clean it up with water and it's non-toxic too.
