Idk how it is where you guys live, but here WD40 is by far the most popular - I just always presumed that it's because it's the best.
The argument that the fluids couldn't do their job at optimum because it wasn't done over several hours applying multiple times - I think it's irrelevant because when you need it, you'll rarely have so much spare time. Even that 1 hour was unrealistic imo.
Just thought it interesting.
