I built a small cedar shed last fall out of cedar siding -- this stuff if you care:
So, how do I repair this -- a bunch of acrylic caulk? Wood putty? It's on the side of the shed and while the shed is a nice looking structure the side with the hole faces a bare bank of dirt and doesn't get much or any of my wife's glances, so it doesn't have to be picture perfect. But I would like it to be weatherproof, more or less and "attractive as possible" without going to a lot of hassle.
