I used my crox spray for the first time last weekend on a hard wool felt strop. Do I have to spray it again when I decide to freshen the razor again? I thought it could use a fresh up since I used the same razor for3 weeks straight. Fixed that problem and got another one! Is about 3 weeks the time you would strop a razor with the crox spray? Is diamond spray better? Can I ruin the edge if I strop to much or to early with the crox? Thank for all the help!
