I have been professionally spraying material for almost 40 years and for small jobs this is the way to go. The interchangeability is the key. When spraying, it's important not to let the material harden in the gun. After spraying any kind of finish, I remove the first container and put on a container of thinner and spray the gun clean. If I cap the first container with the orange plug, it will last even overnight.One of the things I found most satisfying is using this process for matching a stain. We all know how time consuming it is to apply a stain, clean the gun, change to a new stain, etc. With the 9 oz. interchangeable containers I can speed up the process greatly. They are not cheap, but they are very well designed and made. I have not found a problem yet; they are well worth the price. I would recommend this product for anyone who has to spray and doesn't want to have to clean their equipment over and over again.
