Couldn't agree more, Duncan. In the long term, the last thing you need near an ignition system but, it seems, others know better so you pays your money and you takes your choice

Steve, in the 80s and 90s over 20 years as an AA patrol I found that WD40 was very useful with dizzy caps and in particular the poor HT leads that people had fitted. Damp foggy weather needed something to deal with the damp ignition systems, especially when cars were parked with engines up against a damp hedge or bush.
Removing leads and drying in hot air from the van heater could get engines started, but they'd be as bad after a few days. Drenching leads in WD meant they were ok for 12 months. Never known WD to become hygroscopic.
