Determine location of leak in waders (With waders inside out, spray general area with rubbing alcohol. Look for dark spot on the outside of waders). While indoors or shaded from the sun, apply enough UV Wader repair to coat damaged area, as well as the area around each hole. Expose to sun light or use one of Loon's UV lights to cure. In direct sun (or when using Loon's UV Lights) hardening should take approximately 15 seconds.
