Just got back from Cablelas, the bargain cave to be exact...got a deal I hope on a pair of breathable waders...they look like the cabeleas version of the G3's...they were marked $51.99...from the normal price of $300.oo...the lill tag said returned for leak...I looked them over could not find a rip ect...took them home filled them up with a gal. of milk and twisted the boot part no leak there..now my question...I remember hearing about something to do with alcohol and checking for a leak..what is the trick?...i have already tried the dark room and flash light thing..anyone ever hear of the alcohol trick?
