Finishing - where to start?
A finishing is applied in the first place to protect your instrument. Not only against damaging by bumps, but also by conserving the wood. The finish however also gives a look and feel to your instrument. Will you go for a subtle, natural looking finish, a traditional French polish or for a stunning gloss for your guitar.
Once you decided on your choice of finish, you need to consider the preparation that is suitable for that finish and make sure that you have everything needed for the application.
Because there are many finishes available, we listed them underneath with a handy overview for the prep, app and result to help you on your way. You can click on the products for a further how-to guideline.
