Thick Powder coat
When powder coat is applied too much, it often appears similar to the first 2 images below, a dimpled texture, or a dripping texture. This is caused when the coating of powder is too thick, and when it goes into the oven to cure, the powder melts and starts either dripping or creating a dimple texture due to uneven curing. The 3rd image is a example of a use case of low voltage, where the inside of the corner does not fully coat, so low voltage is needed.

Dwyer MK2 (Airflow measuring device):
The Dwyer Mk.II is a device mounted on the side of the powder coating hood used to measure airflow from the powder booth vent.
