Personally , I prefer Nitrocellulose finish . The finish hardens by solvent evaporation. Each new coat will dissolve the surface of the last coat .So it is easier to repair scratches and knocks. It's durable and the has a warm honey colour , that makes wood look good. Unfortunately the down side is,.....the solvent is toxic and explosive. Most manufactures don't use it for that reason. Also, it never stops hardening and can become too hard , and crack with age. You can make it safer to apply by bruising it on. You don't need a spray booth, spark free spray equipment and so on . But you need to add retarders to the solvents , to make it dry slower, but that lowers the quality of the final finish . It's a skill to be able to brush on ,a thin coat. A lot of cellulose is spoiled by being too thick. Polymers are the manufactures best option. relatively cheep, safe and easy to spray , quick drying , but not as nice looking as cellulose.
