Bob, I didn't say you pushed it. I also understand the concern with damage to paint, which DOT 5 is paint-friendly. I didn't even care for it as a driver fluid. It gives a very strange feel to an already anemic brake system. No need to take personal offence. I know many live on a trailer here. However, I would venture to guess the majority drive their vehicle and disc brakes transfer more heat to the fluid than drum. As you also know it's catastrophic to mix it with any other fluid. Just my experience.
