I too noticed that PVA incorporated in the ground mix for printing on  
Al seemed to leave a rough surface after 3-4 gum passes. The PVA  
containing ground was much sturdier than the one without it but was

I have re-coated the prints with PVA and am doing another pass to see  
how it behaves. Will let you know what happens.
