Well, I could use some more information but I'll add what I could for now.
First off, make sure to heat the object to be painted to 350. I use a small butane torch and it works fine. If you get the blade or jig too hot you will get too much powder on it and it will not look right.
Also, when doing a blade, get some fine wire and wrap the wire into the blades hole, as this will keep the pliers from acting like a heat sync and you'll be able to dip it much easier.
As far as jigs, heat them, dip them and lightly smack the hook off of the jar to knock any excess off of the head.
One MAJOR item that needs to be done to make this work is to bake whatever you dipped! If this isn't done the powder paint will flake right off in no time.
I bought a small toaster oven for this job. If what you are curing is all metal, pre-heat the oven to 350. Once the temp is up, insert the jigs and let them go 15 minutes.
If there is anthing other then matel (such as a weedguard) preheat the oven to 250 and leave the items in for 25-30 minutes.
I*F you notice runs after the curing process it means your intial dip was too long or your lure was too hot.
I don't know what else to add at this time but if I didn't answer your question feel free to email me. I have been using powder paint as long as I can remember.
