My front door used to have a nice varnish finish which was, in a moment of madness, painted white. Then over a number of years was covered in several more layers of the same gloss paint. I'd like to return it to its nice varnish finish. Any ideas of wether I should paint stripper it down to the bare wood or mayve just sand it down to the varnish. I've not had to do anyhting like this before so I'd like to get it started he right way. Taking the door to have it dipped in paint stripper is not an option.
