Made my first jigs yesterday and I have some questions. The epoxy is not holding the weedguards in. I used devcon 15 minute, used a toothpick to rub some on the inside of the hole in the jighead, put in the weedguard and then rubbed a little around the base. It's not holding. Also, how do you keep the hole for the weedguard open while you are powder painting. I am using an arky style jig head with the double collar, and after I dip it in the paint, some of the powder paint around the collars won't knock off and it is not as defined as it should be after the paint is glossy. 

the best way i have found to do this is if you powder paint your jig heads, bake them first. then if you use 1/8" weedguards take a 1/8" drill bit and drill the hole out. be careful doing this because the bit can go deep enough to hang on the hook and spin the jig hooking yourself. same for 5/32". then mix your epoxy and add a little powder paint color you are using to the epoxy and it will match great. then use a wooden clothes pin to snap on from the rear of the hook and it leaves a little v for the weedguard to lay in to hold it straight and also for a stand for the jig to remain upright. sounds like your weedguards coming off is from not getting them deep enough. i never have had a problem since i used this method. i also use the overnight devcon.

also getting to much paint on and it not coming off, sounds like you are heating the head to hot. try not heating as much. and if that helps it will come with practice how long to heat them.
