Your jig is not to hot,reduce the air flow through your fluid bed,and it will not do that,if it was to hot it would bubble up on the jig,if you use a fluid bed to much air creates air pockets in the powder thus creating the surface you have on that jig,I powder coat all my jigs,sonars,one eyes,everything and have been doing this for 20 plus years,my buddy just started and he had same problem,I told him the same thing,also if you have not baked your jig yet just heat it back up and with a rag you can wipe the jig clean and start over,just remember the surface you see before baking is what it will come out as,
