Might seem extreme but I used 'no more nails invisible' which has done the job for the last 5000 miles or so and when dry any excess is invisible as it dries clear which I found useful as it's awkward to clear off all of the excess in such a confined space, I didn't bother unbolting the locker to glue back the treads. The cork/rubber is absorbent and the metal obviously isn't so the two surfaces bond incredibly well.
