I have recently removed the polyurethane original varnish from the fwd and aft cabin floor soles and now replaced it with whittle wax hard wax gloss. I recommend this product so far but obviously time will tell , they quote just 2 coats will last up to 5 to 7 years before needing attention.although Considering most of the original polyurethane varnish I assume is 20 years old but I believe quite lightly used until I came along 5 years ago. I liked the ease of application and low Odour benefits.
