Actually Jimmy, your first impression is the correct one. Tiny holes sometimes won't leak until you're chest deep in the river and the water pressure is sufficient to get through. You can try and try to find the leak on dry land to no avail. But the alcohol trick will find the tiniest leak. An added benefit is the preparation of the area for patching. keep tyin'...byard
