Murray's Liquid Dry Fly Floatant
This liquid dry fly floatant cleans and waterproofs your dry fly in one step. I make this right here in the fly shop.
To use on a new fly, simply dip your fly in the liquid, shake off excess by false casting a time or two and fish. To dress a dry fly that has begun to sink simply blot water out of dry fly with a fly drying patch and then dip into the liquid dry fly floatant and follow steps above.
