- 1). Remove the strings, neck, bridges and accessories from the guitar.
- 2). Sand the surface of the body with 800 grit sand paper until you reach the sealant layer. Sand until the surface is smooth.
- 3). Fill all of the holes and cracks in the guitar body with wax. Drill a 1/2-inch hole in one end of the 1-by-2 inch piece of lumber 2 inches from the end. Thread the lumber into the neck slot of the body. Align the holes in the guitar body with the hole in the lumber. Slide the neck bolt through the hole and secure the nut to the back of the bolt with a wrench.
- 4). Fill a 50-gallon waterproof container with water. Leave a few inches of space at the top of the container so that the water does not overflow the edges when the guitar is submerged.
- 5). Measure 1 cup of Borax and pour the powder into the water. Stir the mixture until the Borax dissolves. Allow the mixture to sit for 30 minutes. Drop one drop of oil paint into the mixture. Watch the paint and see if it spreads evenly and disappears into the mixture. If the paint does not spread and disappear, repeat this step adding more Borax.
- 6). Pour a small amount of the darkest color to the mixture. Continue adding small amount of each color that you wish to use, moving from the darkest color to the lightest color. Allow each color to spread throughout the mixture before adding the next.
- 7). Pull the stir stick through the water using zigzag, circular or wavy patterns until you achieve the desired marbled effect.
- 8). Pick up the guitar by the attached piece of lumber and dip the guitar in the mixture using one steady, downward stroke.
- 9). Hold a portable fan over the top of the container and adjust the fan so it moves the paint away from the area where the guitar is submerged.
- 10
Pull the guitar up with one steady, upward stroke through the area cleared by the fan. - 11
Dry the excess moisture from the guitar using the portable fan. Allow the guitar to dry for 24 hours. - 12
Paint the guitar body with Plasti-Kote using a paint brush. Allow the guitar to dry for 24 hours and reassemble the guitar. Sand and re-coat with Plasti Kote until you achieve your desired finish.
