Field use damage will happen. The easiest tool for maintenance is pure oil. You simply cannot stop the issue from happening unless you have a safe queen. So if the scratches or nicks are very minor in naturn then just oil em with pure tung oil.
Best thing about a pure oil finish is that all you need to do is clean and re-apply....if it is really an oil finish. On a well figured piece of wood IMO it is really hard to beat an old school pure oil finish. But you will need to accept the time it takes to get there.
If the finish is thick (can scratch off), shiny, or can peel then it is more likely a "finish" product which contains varnish. This equals more work than just a maintenance job.
Other fast acting products I have used is Birchwood casey tru oil, or minwax tung oil finish. Both have varnish and dry fast.
Using wax on the finish with buffing will shine it up really well, if that is what you are looking for. Wax needs to be re-applied with use over time and can build up. Buffing wheels help. Wax is more for water protection and looks. It is surface only in its application. In comparison, a good plain ol oil finish can be touched up in minutes, penetrates and seals the wood from the elements. And just plain looks awesome.
My two cents. Have fun with your project and good luck.
