Sometimes you need something to help produce the proper sag in a set of tracks — and you don’t always have something the right size to wedge between a fender and the track. I use foam earplugs: You can can shape them by rolling or squeezing them, then put them where you need them. The foam will expand and hold the track where you want it while the glue dries.
