hi if it helps I have a pewter crash TME midi and a black crash Hug Me. I haven't protected either, and although i use the pewter more than the black although it has smooshed down its still hardwearing - i have 2 small kids and take mine out in rain, the water just wipes off with a towel and it stays fine. i'd protect Sheen or Matte leathers but not crash. enjoy!
