I purchased the standard powdercoating system in April of this year. There appears to be a problem with the gun when spraying. A whole lot of the powder shoots out of the area between the bottle cap anfd the gun barrel. I have attempted to tighten this with the phillips head screw on the inderside of the cap but still throws powder out of the same area. Did I possibly get a faulty gun???? I attached a picture for you to see what the gun looks like just after shooting 1 small item.
