S/B,
I have been tying musky bucktails and spinnerbaits for 25 years.
If you want a good source of supplies, use luremaking.com. Great service, good selection and you do not have to buy huge quantities. They are Canadian, but their prices are excellent.
As to powder painting musky baits -- not a problem. Here are a few things I would suggest.
1) Get a paint heater stripper gun to heat the blades or lead bodies. I used candles and it is messy and a pain in the butt.
2) After heating the surface for about 10-15 seconds, apply the powder in one of 2 ways:
a) Believe it or not, I use a woman's make-up brush -- the kind that are a little fluffly and have paint-brush-like hairs. Dip the TIP of the brush into fluffled up paint and then gently tap the brush over the jig or blade Do that a few times until you have it covered and the paint STICKS. Do not worry about making sure it looks perfect because once you have it covered, genly heat it up again and once you see the paint start to go glossy, back off on the heat. When you are applying the paint, I put hold the thing I am painting in a vice. The as you tap the paint off of the brush, hold the jar UNDER the object you are painting to capture any unused paint.
Take a small container with a plastic or metal lid and poke in a few small holes. Then do the same as above, but shake the the pain over the object like a salt shaker.
