Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit
during cold temperatures, warm the kit in a heated
environment for five minutes. This will help to inflate the
tire faster.
