Five Hours and Counting
My T/F shoe covering is worn off and it does not get hot enough anymare been using it since 1981
used it to cover my skypup U/L 40 yards of material
then a Murphy renegade 42 yards
and countless models
then got a Tower hobby one cheap and made a couple dokens holes in various covering (killed it recently)kept varying in temp.
using a hanger 9 electronic model now for couple of years
realy like it maintains temp within a few degrees and setting knob quite precise
