I spray the outside of the waders with rubbing alcohol. Turn wader inside out and then look for a dark spot on the inside of boot foot area. Use Aquaseal on the inside of the wader at dark spot will keep your wader looking new.
Fill a bathtub with water and turn the waders inside out. Blow air into the leaky wader leg and twist the top of the leg on the side of the leak waders to keep the air in. Submerge boot foot area and look for bubbles. Repair on inside of boot foot.
