I like to use just enough heat to get the powder to melt to the head. Start counting and try to do a minimum amount of time to where the paint is not sticking. Then add a second, and so forth, until you get it to just barely melt. After that I pass the painted head over the heat very briefly to ensure it is indeed melted on.
Most paints bake at about 325 for 20 minutes. However, some need more heat and for a longer period. Usually 350 for 20 minutes covers the spread nicely.
If the jig head has blemishes, your powder paint will reveal those. I file my jig heads to remove these. If you start filing your heads, keep a few things in mind. One is that this is a great time to get lead poisoning. Try to keep the work area clean. I lay down some paper towels to catch the filings, and then ball the mess up after I am done and toss in trash. Scrub your hands clean when completely finished.
I dip in the jar because using a little extra paint doesn’t bother me. The fluid bed bothers me as it makes a huge mess. The extra paint helps cover blemishes.
Little practice and you will be knocking out some nice stuff.
Maybe they will bite this one……
