Doing a few tests on a window using shellac. This is a very old school method of varnishing timber surfaces. Most peeps will also know it as the process of French polishing.
ABOVE: This is what the old surfaces look like after many many years. Hey
This is what it looks like now just like magic ⚡️
Shellac is produced by Beatles onto a tree where it is scrapped off in flakes. Once mentholated spirit is added the liquid is then applied in very this layers. The more layers the more colour, this seals the timber and keeps it weather proof. And can be sealed with a polish after for a higher gloss level.
