been having probs w slo leaks. Got some newer 14" stock type tires going onto steel rims, they're a bit rusty & I hit em good w a wire wheel on a drill. What (if anything) should I use on the beads to help insure a good seal. I'm tired of this crap. iirc a guy suggested used motor oil?? but I wanna check for sure before I do them. Thank you for your time.
