If you take care of it, it should take as long as your decoy. The foam tail is made of urethane foam, not polyurethane. It’s UV stable. It’s closed cell, so it doesn’t absorb moisture like a sponge. It’s flexible, so it won’t break. In other words, it’s durable, it doesn’t “wear out.” If you bend it many times, the paint may start to look worn. But, Gary Clancy, CJ Winand and others don’t even care about the paint. They use it with the “white” side showing anyway. It’s possible, however, that if you leave the tail outside, that some critter will chew on it. But it will still work.
