Fishing salmon & trout on Lake Michigan, and this time of year the water fleas are terrible! Last week they were so bad that the sport fisherman and the charter boats were complaining that the fleas built up on the line so bad that the guides on the rodtips would plug up and you couldn't even reel in. Fisherman were having to handline the fish for the last 100' to 200'. That can be awfully tough on the hands when you are are trying to boat a 25 lb. king salmon. <br /><br />I was wondering if spraying WD-40 on the line would prevent the buildup of water fleas?<br /><br />Anyone know if WD-40 would cause monofilament line to deteriate?<br /><br />Buck
