Tru-Oil is a type of finish that is commonly used for guitar necks, bodies, and other wood surfaces. The curing time for Tru-Oil can vary depending on several factors, such as the temperature and humidity of the environment, the thickness of the finish applied, and the type of wood.
It’s recommended to let the Tru-Oil cure for at least 24 hours before applying additional coats. After each coat, it’s also recommended to lightly sand the surface with fine-grit sandpaper to promote adhesion of the next coat.
It’s generally recommended to apply several thin coats, rather than one or two thick coats. This allows the finish to dry and cure properly and also helps to prevent runs and drips.
It’s also important to note that the curing time for Tru-Oil is not the same as the drying time, which is the time it takes for the finish to become dry to the touch. Drying time can vary depending on the thickness of the finish applied, but it’s usually less than 24 hours.
You should wait until the finish is completely dry to the touch before applying any additional coats. It’s best to wait 24 hours before handling your guitar, but it’s recommended to wait at least 5 days before polishing or buffing the surface.
It’s also recommended to wait at least a week before exposing the guitar to extreme temperatures, humidity or sunlight. This will ensure the finish has cured and hardened properly.
It’s also important to note that Tru-Oil is a relatively slow curing finish, and the curing process can take up to several weeks, depending on the conditions.
