Subject: Re: SHARPIE PERMANENT MARKER ETCH TEST FOR TOUCHUP NOT PLOTTING

From: "Dave Sage" <davesage12@...>

For touch ups I would suggest, with the right ink, thetechnical pen would be far superior to a sharpie because you can just set thepen tip down and ink will flow. No need to rub it around. I always foundsharpies difficult to get a good / durable layer built up. The tech pen ink usedto be much more resistant to etch as well. I see the bottle I have is Staedtler#485 23SAR-9. The R may be a P. There's a bit of ink dried on the container. Agoogle search on anything to do with technical pens draws a blank as far as Ican see. Staedtler does still have a selection of "sharpie" typemarkers that may be better than an actual Sharpie.

 I believe they also had a technical pen ink that wasused somehow in the ceramics industry. Maybe to autograph mugs or something?

That may be another place to look for a good ink.
