"""" Keep in mind that gumtwo's seat cover pattern is sewn not heat pressed. For those of us that live in wet climates that will make a difference. Water can seep into the sewn pattern but the heat pressed is as water proof as the material itself. Once the foam gets soaked it takes forever to dry. """
Very good point ,and considering that some of the K model seat pans have a rust out issue in the front any way..
I have used two of Gumtwo's( 78 550 K's) what I have done too make install easier, is put plastic between the cover and the foam,not for water resistance which I never thought about ,but too make the cover slide easier.
So hopefully with the plastic I now have an extra barrier,
Next seat I will have to give Pit -replica a try.
