Turn your waders inside out and locate where you believe the leak may be. Get a spray bottle and fill with rubbing alcohol. Liberally spray the suspected area(s) with a fine mist of the rubbing alcohol. Wait a minute. Any leak, scratch, tear will appear as a blueish/purple spot(s). Mark with a Sharpie Marker and let the area completely dry. Apply Aquaseal to pin holes, "scratches" and let dry over night. If you suspect a more significant tear, you can liberally apply the Aquaseal over the tear. Place patch over tear/Aquaseal and add additional Aquaseal to the perimeter of the patch. Let dry over night. If you suspect a leak in the neoprene bootie or on any seam, we HIGHLY recommend bringing them in and we'll send them back to Simms on your behalf.
