I just picked one up (Primos the freak) just wondering, do I have to sand it everytime I use it? I notice after I sand it, if I wipe it with my fingers it no longer produces noise until I sand it again. Is this normal? Will this happen everytime I touch the surface or will there come a point where I will not have to worry about sanding? Do I have to keep sand paper with me on my hunt? Also does it work if its wet? Thanks in advance...
