GC Electronics is under GC/Waldom website does not tell you much
as I believe that you have to be registered dealer to get to most
information on the site. They do give you access to there Dist.
locator but think they are only U.S. and Canada that I saw.

Mouser www.mouser.com I believe carries the GC Electronics resist
pens but don't list them as GC Electronics. They list two pen widths
1/32" and 1/64" or .79 mm and .39 mm. these list for $2.48 and
$2.64 each Page 1040 in Cat.#615

MG Chemicals has a resist pen www.mgchemicals.com I buy MG
Chemicals thru Circuit Specialists www.web-tronics.com MG
Chemicals pen is only listed for use with Ferric Chloride and Sodium
Persulfate, not for use with Ammonium Persulfate.

These pens look just like a Shapie, in fact I use a fine point
Shapie to do touch up when needed on my boards, I use Ferric
Chloride Etchant.
