The faster drying time allows for more efficient layering and completion of the finishing project.
The application of numerous slender layers is critical. These attributes directly translate to an instrument that not only looks superior but also performs optimally, retaining its value and appeal over time. Adherence to this principle is non-negotiable when seeking professional-grade outcomes.
2. Wood Grain Enhancement
The application of a particular oil finish to guitars is inextricably linked to the enhancement of wood grain. The finish’s composition and method of application allow the natural figure of the wood to become more pronounced. This is not merely a cosmetic effect; it directly impacts the perceived depth and character of the instrument. An oil finish penetrates the wood fibers, saturating them and causing a change in the refractive index, which results in the amplification of the grain’s visual impact. For instance, a flamed maple top, when treated with this finish, will exhibit a more striking and three-dimensional appearance than if coated with a thick, opaque material.
The degree of enhancement is also contingent upon the wood species and the quality of its grain. Highly figured woods, such as quilted maple or burled walnut, will naturally show a more dramatic transformation. However, even less dramatically figured woods benefit, gaining subtle depth and warmth that other finishes might obscure.
