Hi Quwatha. I am not sure. Maybe some others who read this will know. Is the ink on paper? When I use Tombow brush pens which is black water based ink I do not use any sealant.

I have used Krylon UV spray for a gouache painting on Aquabord before very successfully. Gouache probably reactivates/runs worse than anything I’ve ever used so I would think the Krylon would work with the brush pens. However, I would try first with a piece you don’t particularly care about.

The secret is to lay the piece flat then use a very, very light spray to seal the ink first. Spray from at least 12 inches above the piece and let the mist gently settle on it. Then use at least three light coats after that.

If you try it, please let us know how it works for you.

Thanks for that information, Wassie!

another thing you could experiment with on a quick sketch on the same paper is beeswax polish

One of my students experimented with this over watercolours and it doesn’t move them at al but gives a soft sheen and protects them. Rub on with a soft rag.

Oooh this sounds like a good idea to try!

Thanks for all of the info. The tip about spraying a light coat of sealant first is very important. I tend to be heavy handed and have messed things up by blasting them with the spray!

One more thought. I didn’t apply a seal coat of spray varnish prior to the Dorland’s Wax. That may have prevented Noodler’s from smearing.
