There have been some concerns expressed in the Fora about the use of WD40 in an enclosed space such as an engine bay.
The manufacturers do not seem to have a data sheet available for the English product, but there's one for the USA.

OK, it has its excellent uses as a lubricant and water displacer, but as a overwinter preservative or rust inibitor, there are products which are less volatile, more effective, less flammable, and less environmentally damaging.
I note that the Flash Point of 131F is below the operating temp of many engines. Whilst it may not always catch fire at that temp, it will certainly evaporate key distillates.
