Before my wedding, a friend and I made a pretty nifty arch type thing out of reclaimed lumber. The original idea was to use it for the wedding and then have it sit at the bottom of our walkway in front of the house. Of course, in typical husband fashion, it has sat in my shop for the past 5 years. I'd like to have the space back in my shop and I'd like to finally get it outside where it belongs.
However, one thing we never really accomplished was deciding what kind of finish to put on it to protect from the elements while outside. Up here in the northwest "elements" means drizzling rain for 7 months and steady sun for 3 months. Fall and spring last about a month each if they arrive at all.
I am crappy at identifying wood, but my best guess is that the wood is fir. I can take some close up photos of it if necessary.
I'm not really looking to stain the piece to any other color, just to protect it. I'd be interested in hearing any and all suggestions.
