Found the glue wouldn't hold the brown paper (peeled easy)
Used minwax water based (told you can use Klear floor wax)
Much better results
Just as hard
Glad to see you making headway with the HK foam
It`s very difficult to prevent tearing of the soft HK foam, I use a Swann Morton scalpel and number 11 blades and you need a cutting pad underneath the foam to save the sharpness of the blade.
I use those cheap thin polythene kitchen cutting mats.
