Almost done powerwashing the deck -- about 1,500 SF. Deck is

advice on what to use for finish. Waterseal? Deck stain? It was
unfinished/unprotected by the previous owner. Will one coat cover and
protect?

Thompsons and the like are less than useless. If you're going to put
something on it, a *good* solid pigmented deck stain is the best, IMO. If
it's in *really* good shape you may get away with a semi-transparent stain.
This is one area that you get what you pay for. With 1500sq. ft. you're going
to pay.

I don't want to do this for another four years.

Good luck with that.
