You don't have to hot flock ANYTHING if you do something is wrong somewhere. Take a new test panel and shoot it with a powder and cure it. After it cools apply a second coat to it I guarantee it will go on with no problems. You should have wiped down that part with denatured Alcohol before you shot it cause touching (bare hands) it before coating WILL cause attraction issues if the oil on your hand or some other contamination gets on the part. If you are going to try and trouble shoot you need to eliminate all the variables you can. That means you need to get a new panel and note your prep methods, gun settings, and cure schedule that you are using. This way if something happens on the test panel you can pin point the issue more easily. If I were a betting man I would say bad ground or surface contamination. Anyway shoot a blank test panel and get back with us, good luck!
