Stans Race is just regular sealant with perlite in it. You can just throw a scoop of dry perlite int he tire and use whatever sealant you want. I love Stans build something from the hardware store approach, but that also means it is easy to reverse engineer.Stans Race sealant can't handle the injector. Pain in the ass. It works great though. Worth breaking the bead for. I use a CO2 cartridge to seat the bead again. Totally worth the effort.
