The finish probably is one of the most important step for an instrument.
It is a protection against the damage of the time and marks, and reveal the beauty of the wood. As I always say, you could build the best sounding guitar with the best material you could find...but if the finish is a mess, nobody will ever buy it.
Since the end of 2019, you now have the choice beetween 2 different finishes:
After a masterclass with Michel Pellerin (les guitares Pellerin) at the end of 2019, I am now able to finish my instruments myself. In the past, I've used polyester finish on my guitars, but I decided to go with Polyurethane for a couple of great reasons.
The product I am using, allow me to have a gorgeous result, strong & durable, with the highest standards. The thickness of the final product, is as thin as possible. It allow the instrument, to reach optimal results in terms of sound & durability.
Ever since I have embarqued on this journey, I had the time to try a lot of different finishes; True Oil, Water Laquer and French Polish.
This old technique that is French polish has been used on instruments and furnitures for a long time, and it is still, to me, one of the best technique to apply if you care to have not only the best sound for your instrument, but also the best aesthetics. Unfortunately, this is very fragile.
The shiny "3D effect" you get from French polish off the wood is unbelievable. It also provides an easy-to-fix finish should any scratches or blemishes ever surface.
Though a hard and long required process, the French polish is one of the only varnish that will match the standards that I hold for my instruments... but as I said previously, it is more fragile than other finish. That's why I offer other great options.
