I coat a lot of jigs at one time, so use some small silicone caps that I get from a powder coat supply store. I bought several hundred of them in the sizes that I use. They make them in various sizes, and they will fit most hooks. For smaller size hook eyes, or those that the caps won't fit over, I wrap them with teflon tape, that I buy from Harbor Freight. The tape is not expensive, but takes time to do, but the results are great, as it results in completely clean eyes. I'll often do that at night when I would not be doing anything anyway, and can wrap a few hundred jigs in a short time. I have a tackle business, but that's not time I include in my costing, since it's time I would be wasting anyway. this is something I learned many years ago, when I was only making jigs as a hobby, and just continue doing it.
With the silicone caps, they're also reusable, and can be quickly slipped over the eye on the heated jig, dipped in the powder and then remove the cap for curing, or I have put the caps on the hook eyes and hung them in my oven to heat them for coating. The heat doesn't hurt the caps, but they do need to be cleaned eventually.

The thing is, we all develop ways to accomplish the same thing, and what it boils down to is what you're comfortable with doing.
