Hello--

At the risk of revealing the era in which I learned technical drawing 
(*), how about using an erasing shield?

The online auction site lists a bunch of sources for $.99 on up...

(Usual disclaimers apply.) Also, I haven't tried this due to displacement of
my drafting kit<g>.

In theory, the marker ink shouldn't spread under the shield and smear, 
but if
so, applying some tape on the under side to raise the shield off the 
copperclad
might work.
