I am planning to have a built-in dining seat removed from my trawler to make more salon space for more comfortable seating. The floor is finished off the same way under the seat, but the presently exposed floor is in bad shape. Lot of scratching, some areas lighter than others from sun fading. I was thinking I would belt sand the floor, then stain and varnish. The flooring is fine under the old finish. Any thoughts on what products to use for this project would be appreciated. Thanks
