try a two part rod epoxy like flex coat lite or even lite thread mater any thing lite so it does not build up as much. what i suggest is mixing it with the syringes that are graduated for rod finish like that flex coat make and sells. all you need is like two pea sized amounts but they got to be mixed 50/50 or they will not harden up... now two ton and 5 minute is the wrong way to go they harden and turn yellow to quick.. you can get the rod finish at mudhole.com etc.. etc... all i do is apply it with a tooth pick before i tie the fly then let them hang upside down make sure the wipe excess off every ten minutes for the first couple hours. so it does not leave sags on the jig head. i use a block of foam i got tooth pick in to sit it on the tooth picks stuck in the foam and set the foam upside down on the tooth picks... any ways mix the epoxy for like 5 minutes with a tooth pick real slowly not to create bubbles if oyu use a brush to mix it the brush end will create bubbles just a tip. mix till not marbled any more then apply. it easier said then done i am sure you will get it done...by the way you can tie thousands of jigs with just one 4 ounce kit of "epoxy rod finish" any ways wish you the best.
