I have an early bottle of NuFinish (and NuVinyl) that hid for decades. The dated and simple style obviously done on the cheap, before they had much of a following or art budget.
Both perform like a new bottle fyi.
Pledge is pretty docile. It has some oils that plastics and some paints like to absorb, usually in a good way. Extremely unstable porus paints might be brake down by it, but these might fail with dishwater water on a cotton ball anyhow.
Try cleaning a plexiglass window with it if you have one. You'll notice the small scratches become.cleaner and clearer as it fills. Mildly smeary, but looks way better than Windex amonia damage imo. The cloudy look that forms over time is partially oil breakdown and dryrot from ammonia or so I was told. It seems to work for me for a lot of things for decades now.
