Well ; I should NOT bite on this one for exactly the reasons Steve
pointed out ;
but I can understand someone fighting off a reverse engineering for
enough time to get some distance (deserved) .

So , let's face it , any decent chemist can remove almost anything from
anything ;
black epoxy would not stop me ; sorry Steve ; there are real nasties out
there .

Edwin , I did NOT give you this tip :
You know those 45' inclined IC formers ? > pop a tube on top , take from
bottom ?
If you incorporate a fine EARTHED high speed steel brush into the path
and play a bit with frictions on feed & exit ;
with a vacuum nozzle by the other side ;
you're home .

Hey, Steve , thanks for sticking out for me when I thought I'm in ....
    .

See you folks
