That slime stuff is shite.
Use ULTRASEAL, seals all punctures and no more slow leaks, will seal up to 6mm holes so screws etc can just be pulled out.
When I saw this stuff demoed to me it had 50(FIFTY) 4mm punctures put in the inflated tyre at 32psi, tyre was then spun and sealed perfect but did lose 1psi!!
No more scrap tyres as the "hole is to close to the edge" etc just pull out object and drive, safe for all cars and bikes, used in NI for the troops, amd also STINGER PROOF(it seals the tubes!!) so useful for any budding bank robbers.
