Thanks for the referral to Nealey. Just ordered their Mini kit. I have also relied on Stop n Go plug kits and they have worked well for me, except for my misfortune a couple of times where "tears" couldn't be fixed with a simple mushroom plug in an emergency. I've removed both bike and auto tires and patched them successfully on the inside for my own comfort rather than relying on plug or rope fixes. My first test of the Nealy will be on my RAV4 spare which has a slow leak from a staple and needs air every 2 weeks or its TPMS goes off.
