Is scotch bright better for to use on slate calls than sandpaper?

I just use sand paper. Seems to work fine. If you want a rougher surface, just use a more coarse sand paper.

I use plumbers paper on mine.

I use the green Scotch-Brite pads on my calls. I cut them into smaller, manageable pieces. You have to be careful using sandpaper on slate calls as you can actually wear the slate thin with sandpaper with too rough of a grit. Fine sandpaper works good for an initial dressing of the call occasionally, but the Scotch-Brite is what I take to the woods with me to touch up the call now and then.

I use sandpaper to rough up the surface once in a while,but it is the scotch brite that I take to the woods with me.

Just my opinion but the rougher the surface the better the call sounds.With some of the newer surfaces like crystel and fricionite it takes a fairly coarse paper to scratch the surface.

..i have a new glass friction..that has been tough to get rough..any sugestion???

Totoe,For the first roughin up on glass and frictionite I use a sandin stone after that I use emory cloth(plumbers sand paper) A whole roll costs about $2 this works pretty well for me

I attended the Eastern Outdoor and Sportsman Show in Harrisburg, Pa. a few weeks ago, and while looking at the Freak calls at the Primos booth I noticed they really had them roughed up, and they sounded great. I asked what they used, and they told me the Slick Stick (by Primos of course). I bought one of these and conditioned my glass call and also the original Freak call that I have, and they sound really good. The Slick Stick has a diamond cutter side, a sanding stone, a port to stick your strikers in to rough them up, and it holds your box call chalk and 2 more conditioning pads inside. It's a really neat tool and cost somewhere aroung $10.00. The guy at the booth said he uses the diamond cutter side first on a glass call and then goes over it with the stone. Try it, you'll like it.

I agree with most, the rougher the surface the better. I like to get a lot of sound out of the glass call and that seems to work best by using courser sand paper.
