35" tub should be a 41qt... I use 12" of 11" flex.
I tape all 4 sides with 1/2 tape overlap just like others.
I do TRIPLE up the front edge with 1/2, then 3/4 then 3/4 coverage to serve as a "sacrificial" surface. I have yet to notice any wear on the tape from the tubs BUT I figure it is better to be safe and maybe last longer.![]()
