Some suppliers are easier to deal with than others. How good are they at giving you tech support and helping you to get dug out of a hole. It is he who should be working to always improve and develop his hand-eye coordination so that you get the most out of the way that these finishes go on and how they look upon completion. Once you decide to advance from nitrocellulose lacquer to a catalyzed coating, the world of finishing becomes more complex. Some of these coatings are very temperamental, and each coating behaves differently according to how the manufacturer formulates that coating.
Many shops elect to work with finish suppliers who custom-formulate the catalyzed coatings.
The formulations are done in such ways that they meet the specific needs of the shop or factory. They could be formulated because of certain temperature or climate conditions, a certain open time that the finish room needs, a certain finish schedule with glazes, a certain recoat window or potlife, etc. Summing up, those two essentials are your supplier and your finish operator. Those two matter more than suggesting a specific product, which may work peachy keen for my needs, but your needs may be different, making those products not the ideal products for you. It is just not as easy as picking a conventional lacquer to coat your goods.
