As low emitters of volatile organic compounds (VOCs), they’re gentler on our environment and pose less harm to human health. Available in glossy, satin, and matte varieties, these finishes cater to an extensive assortment of artistic tastes for guitar enthusiasts.

Applying the finish is as simple as spraying or brushing it onto the guitar’s surface, similar to other finishing methods. Once dried, it forms a crystal-clear, sturdy protective coating that elevates the wood’s aesthetic appeal.
