Had front door chemically stripped of it's 10 or so layers of paint, with the intention of re-painting. Turns out that it is original c.1900 door and looks great just as it is. What treatment would be suitable that would not alter the look? (i.e. not shiny varnish, coloured wax etc..) Any suggestions appreciated. BTW .. no idea what type of wood it is, it has a pine look to it.
