Meet the newest addition to the Slime tyre repair team Slime Assist! With this compact, pressurized bottle, it only takes an air source to repair your emergency flat. You don't even need to remove the valve core! Here's how it works: Attach the repair sealant bottle to the tyre. Then, connect any air source of your choosing (tyre inflator, gas station air, air tank, etc.) to the sealant bottle and turn on the air source! The hard, plastic bottle is designed to withstand the pressure of the air as it moves through the bottle and pushes the repair sealant into the tyre. No jack, no mess, no hassle. Works as a universal repair sealant for all standard-sized vehicles.
