I've heard from a few sources that once you have used a Spark-Lite and the coating on the striker has been removed, it will begin to deteriorate. I have used my Spark-Lite from my PSK on a few occasions, but I have not touched it in several months. It has just been sitting in my PSK waiting for a time when I might need it. However, now I am a bit worried that when that time comes, the Spark-Lite will simply crumble when I try to use it. Should I get a new Spark-Lite and not use it until I really need it? Or will this one hold up fine?
