Guitar Finish Types
Polyester Guitar Finish
Polyester finishes have been widely used in guitar manufacturing since the 1950s. They are typically applied as a topcoat over a colored base coat, resulting in a high-gloss appearance. Polyester finishes are known for their durability and resistance to scratches and stains. They are also relatively easy to apply, which can make them a cost-effective option for guitar manufacturers.
Applying a polyester finish typically involves spraying on multiple thin coats until the desired thickness is achieved. The finish is then sanded and polished to create a smooth and glossy surface.
Polyurethane Guitar Finish
Polyurethane finishes have become increasingly popular in recent years due to their versatility and ability to provide a more natural feel. They are also known for their excellent protection against weathering and aging. Polyurethane finishes can be formulated to achieve different levels of gloss, from matte to high gloss.
Polyurethane finishes are applied in a similar way to polyester finishes, typically as a topcoat over a colored base coat. However, they may require more preparation and care during application due to their tendency to yellow over time if not properly cured.

The Benefits of Polyester Guitar Finish
Here are some of the benefits you can expect from a polyester finish:
- Durability: Polyester finishes are incredibly hard-wearing, making them ideal for players who use their guitars frequently. Unlike some other finishes, polyester can withstand heavy usage without wearing down or scuffing easily.
- High-gloss appearance: Polyester is known for its high-gloss finish, which gives your guitar a sleek, professional look. This finish looks especially good on darker woods, such as mahogany and rosewood.
- Resistance to scratches and stains: Polyester finishes are incredibly resistant to scratches and stains, which is great news if you’re someone who tends to be rough on your guitar. Polyester can resist most common types of damage, including chips, dents, and discolouration.
Some of the cons of using a polyester finish on your guitar include:
- Lack of natural feel: Because of its thickness, polyester finishes can feel somewhat artificial to the touch. This may not be a problem for some players, but those who prefer a more natural feel to their guitar may find it somewhat off-putting.
- Difficulty with touch-ups and repairs: Polyester finishes are notoriously difficult to repair or touch up. While scratches and dents can be filled, the repair process can be time-consuming and expensive, making it important to take good care of your guitar from the outset.
Overall, polyester finishes represent a solid choice for players who value durability and a high-gloss appearance. Just bear in mind that it may take some time and effort to maintain your guitar’s finish in top condition over the course of its life.
