I had to fix a couple of freeze breaks in a tiger river spa that I bought used.
I had to dig out a fairly large amount of foam and I am finally at the stage of reforming the underside of the tub.
My question is what type of foam should I use?
Great stuff sells a couple of different kinds... Low window expendable foam, normal expendable foam, and High expendable foam.
Is there some kind of special stuff I should use?
Thanks Greg
