Slime vs Tire Repair kit I repair all my auto flats using a tire repair kit. Kits are usually less than $10 and I can use it for 8+ repairs. Works great. Slime is a mess, it does work and costs about the same but maybe not as many repairs. I haven't had a mower flat yet (/crosses fingers) and was wondering if anyone else uses the tire repair kits on their mower tires and equipment tires. Or do you prefer Slime?
