for every batch you do, if you take 1 or 2 bullets, and do the hammer smash test on them, it will tell you if you have good adhesion and cure of the powder coat or the HITEK coating. I can tell you that in the long run the HITEK coating from Bayou Bullets is cheaper. I did 1000 bullets today and used maybe 3 oz of mixed product (Acetone, coating, catalyst)
