1. As carbon comp resistors are stored they tend to absorb moisture. When they go through wave soldering process increases the resistance value significantly in lower ohmage resistors. In many cases this resistance increase is permanent. When it is permanent does it cause any physical damage?? Or change any operating characteristics?? It is not practical for me to store these in a dry environment. 2. I've been told from time-to-time, the main reason carbon comps are used because they open when they fail. Is that an old engineer's tale?? What would be a good subsitute??
