I really thought I had tried Sharpies previously and they didn't

I must have tried a dozen markers. Guess I got my markers mixed up.
But I just tried several Sharpie colors. All work well.
And as you say, a little alcohol (isopropyl was all I had handy), does
indeed wipe clean.
FYI - Dark blue seems to dry the fastest, though all dry acceptably
fast enough.
I'm going to let some test samples "cure" overnight and see if they
still come clean in the morning without scrubbing.

They may take a bit of soak time, but I've taken years-old sharpie marker
marks off with isopropyl.

A good coat of 'Turtle Wax Paste Wax' will seal the surface and make
it a lot easier to clean. I made some custom 4' * 8' dispatch &
schedule boards for a company and the wax lasted over a year of daily
changes.

Which is why I said the Mfg remark, because they are so widely used
there. |

Make a rubber stamp, and use printing ink, thick.
Or a painter's tubes. Mix your own color.
Freeze, then flex the bag later, and it flakes off- Hide quoted text -

Interesting idea. Thanks.
But not practical for this situation.
Jim's Sharpie suggestion (earlier) seems to be the right approach.

Use the Sharpie ink for the rubber stamp. :-)
It is only one extra operation. AFTER you extract the sharpie ink. :-] |

Daddy did that too back in the days when everyone was a drug addict.
I always assumed it came from a military origin. |

I don't know the original origin, but I was, in fact, in the military
when I learned it. We'd use the wax markers - what's the difference
between a "China Marker" and a "grease pencil?" - for scheduling and
stuff - the board was plexiglass, and was usually edge-lit - that way,
the wax markers light up. ;-)
Cheers!

Use any newsreader except butthook distress to log into

Took me about three minutes to sign up.

I always assumed a grease pencil was a China Marker??
Are they different?
The China Markers I'm talking about have this little string you pull,
that takes off the paper spiral wraps, and that sharpens it.
I've seen China Markers in pencil form that you could sharpen in a
standard pencil sharpener.
Is that what you're talking about?
And if not the same thing, then I should get one to try it out.
I hadn't previously, because I thought they were the same thing.
Thanks.

There is also grease pencils that have advance mechanisms a lot like a
standard mechanical pencil. Just the same i cannot point to a
reliable statement of the difference. |
