Can someone please describe how I can tell the difference between a crack and a scratch? What I have is a pse nova with a coulple 1/4-1/2 inch splits/scratches you can barely feel them when you run your finger nail across them and there is not any splinters or sharp edges on them. Also these are on the flat part of the limbs and not even close to the sides or the cam. one limb has one on front and it goes horizontal, the other limb is on the back and it goes vertical. Any help would be great.
