Bought this gun after being charged a $120 buckets to powder coat a few small items. Went and bought a cheap used kitchen oven. Powder coated my first few items for a 59 Ford I'm restoring. They came out amazing. The process is fast an almost fool proof. If you prep the part correctly and what I mean by that is remove all rust, paint and grease then the actual powder coating is simple with this gun. The powder is fairly cheap and goes along way. There is very little waste and practically to smell. Your only limited by what will fit in your oven. Highly recommend this gun if your are restoring something.
