Hi, was wondering anybody could give me advise on what is best to use on my exisiting bannister. Currently it is a mahogany color and I'd like to keep it this way. Therefore, the option of sanding down to the bare wood isn't really what I want. What do I need to buy, in order to give the existing bannister a new glaze so to speak. Bit confused as to whether to use Lacquer, clear varnish etc. Also, what best to use in terms of whether a brush or some kind of sponge? I don't want brush strokes to appear. Any help would be much appreciated.
