I put a number of pig statues in my flower beds every year. I actually discarded a few of them this Fall, as they had become "distressed" beyond repair. There are several metal pigs that I've been meaning to clean up and repaint for a couple of years, and I decided that it was finally time to bite the bullet and actually do it.
They were looking pretty bad, faded and rusting.
Then I gave them a couple of good coats of exterior spray paint.
It took me a long time to get the details painted back on, and they didn't turn out as nice as I had hoped. After a couple more coats of clear coat, they should last another couple of summers out in the flower beds!
