I agree with the others. If the wool felt is your only material, and for daily use, then No. Do not spray or paste it. As far as the Leather goes, Just a rub down with the palm of your hand. SRD Premium 1 is high quality leather. It needs no treatment...To be honest, You should have got Linen or Cotton for daily use, and then purchase a seperate wool felt strop. They are wonderful for sprays, either the Diamond or the Chromium oxide, both available at SRD. What I would do, is buy another piece of material from SRD. You can buy a piece of Cotton or webbed fabric from them, You might even be able to fit it in your existing strop.
