Jim, I am with you and Ed on keeping the original wood. Especially since you have already sanded and put one coat of spar on it. You can always add new wood later if you want but that old wood has character and reminds you of the life this grill has already gone through. It’s looking Good!I'm leaning towards keeping as much of the original as I can. If not why have an old grill besides of course they are better than new ones.
