to be honest im not good enough at it to be comfortable charging someone. I still struggle with getting aluminum parts coming out perfect. Steel brackets and other things i get to come out fine. I seems that i cant get the aluminum clean enough. I run them through the parts washer, media blast then wipe down with acetone and still doesnt seem clean. Next time i will try all the above then bake in the oven. Let part cool, wipe with acetone then see what happens. If anyone has more experience with powder coat let me know where im going wrong.
