Got a 2012 Master hot tub. Sprung a leak. I need to rip out at least some of the insulation. I am thinking of ripping it all out and redoing it. I live in Canada and it gets down to -35C (-30F) once in a while. We use the hot tub all year.

Anyone got some recommendations on what spray foam to use? How much would I need?

I was curious if any one has compared non-ethanol fuel to 10% ethanol? Mostly intrigued if you saw any gains in fuel mileage. Did you notice anything else?
