What I do get my mileage from is 3M micron paper (I get mine from Rio Grande).
I have to agree whole-heartedly! I don’t do platinum, but this
stuff is indespensible in my work which is all fabricated. I use
mostly blue and pink, occasionally the green when I need
something more aggressive. (I use silver and gold in my work). I
do not need to use anything else but rouge since going to these
micron-graded abrasives. Saves me much time. (Rio, too. I
don’t work for them)
