I'm going to be pressure washing and sealing an existing deck before winter and am considered sealing it with linseed oil. I'm interested in linseed oil as it's used on wood trim on yachts. I'm looking for a natural finish that shows the grain and has a shine to it. Does anyone have experience with linseed oil on decking? Should I use Tung oil too? I noticed HD has wood oil for decking at a reasonable price. Any advice appreciated.
