Over the last 2 years we have obtained every rack offered, some multiple times. It has changed our business. We invested in a spray booth. And now are doing more and more spraying, cabinets are a consistent part of our business and we bring passage doors back to the shop. We are a residential repaint company for close to 40 years and because of the door rack system we are making our biggest changes in all these years. The increased production and quality finish are just amazing. After each purchase we thought OK now we're all set. But soon wanted to increase production and saw the need for the next upgrade, each subsequent add-on purchase proved to be just as helpful. Keep up the good work!
