So my house has dark blue plastic shutters. They're about 10 years old now and have gotten faded and chalky. I was going to try and find a close to original color and paint them. I had an idea, though. I had some Turtle Wax trim restore stuff. It worked awesome! Now they're back to almost their original color. You can't tell that they were ever faded. I have no idea how long it will last, but since I plan on selling the house in the next year or so, I will just re-apply when I put it on the market. It took me all of 30 minutes to do the 4 shutters on the front of my house. So there is your GRM DIY household tip for the day.
