Purchasing a performance finishing service will cost more money because of the added time, manufacturing space, machines, and materials for the operation. This painting process requires the right conditions as well. It will push out the lead time a little so don't be in a hurry. We can do this service on products with insulated fireboxes. They also work on square chicken cookers as the heat source is a good distance from the top of the pit. They have plenty of head space. Be sure to use carefully and within the designed temperature parameters. Ask Matt about this. Matt's BBQ Pits, LLC does not guarantee a perfect paint job the life of the smoker or that you won't mess it up, but if used properly can give you a much longer lasting and better finish. The performance finishing service cannot be used on all models.
