Default Dalo Pen replacement

Like many others I've been disappointed with several of the current offerings as Dalo replacements. I have found most, particularly those that are actually "permanent markers" do not prevent etchant damaging (pitting) the wanted copper areas and this is a big problem on very fine tracks. Even the Cif etchant resist pen sold by CPC Farnell is not totally reliable.
I believe I have at long last found a true Dalo replacement - it's called "Pen-touch" and is a paint(not ink) pen. It's available in several widths from Amazon.
I find the fine tip best as it allows the drafting of narrow tracks and larger areas can be filled in if needed. This is a pump action pen with a plastic tip, not just hole at the end of a narrow metal tube. It doesn't run and the paint is quite dense.
Not very expensive either 4.99 including post.

Interesting; I've still got one or two Dalos in my secret place, but cannot count on them seeing me out. That particular pen appears to be widely available; I don't buy from the site you mention.

What are you using to clean it off (acetone)?

That's good to know. I have a couple of original Dalo pens that are still working but I don't know for how much longer!

I have just made a small PCB with a Sharpie pen. It was surprisingly good! I was mentally prepared to have to do it again with a Dalo pen, but no, it was OK.

The Pen-touch sounds good though, especially for fine lines so I'll be ordering one of those for the next one I make.
