In this final installment on finishing your own guitar effects pedals, I demonstrate how to print and apply the waterslide decal to the pedal, and apply a durable clear finish. In previous videos, I showed how to model, drill, and paint the enclosure, and design and prepare the artwork and labels in GIMP.
I use clear waterslide decal paper, and print on my inkjet Canon Pro9000mkII. After printing, and waiting a while to ensure the ink is dry, I spray on a few coats of Krylon Acrylic Crystal Clear acrylic to protect the ink during the soak. Then, after the clearcoat dries for 30 minutes or so, I trim the paper to final dimensions and soak the paper in warm water. When the decal starts to move freely from its backing, I wet the surface of the enclosure and slide the decal directly onto it. I iron out the bubbles with wet fingers, and adjust the decal into its final position, being careful not to stretch the decal.
